How to Calculate Binding for a Quilt: A Step-by-Step Guide
Calculating the binding for a quilt can seem like a daunting task, but with the right tools and a little bit of knowledge, it can be a straightforward process. A quilt's binding is the fabric that is sewn around the edges of the quilt to finish it off and give it a polished look. The binding can be made from a variety of fabrics and can be cut to different widths, depending on the desired look.
To calculate the binding for a quilt, it is important to first measure the perimeter of the quilt. This can be done by measuring each of the four sides of the quilt and adding them together. Once the perimeter is determined, it is recommended to add an additional 10 inches to account for joining the binding strips and joining the ends of the binding tape on the quilt.
There are several methods for calculating the amount of fabric needed for the binding, including using online calculators or doing the calculations manually. By following a few simple steps and taking accurate measurements, anyone can successfully calculate the binding for their quilt and achieve a professional-looking finish.
Understanding Quilt Binding
Definition and Purpose
Quilt binding is a fabric strip that is used to cover the raw edges of a quilt and hold all the layers together. The purpose of binding is to protect the edges of the quilt from fraying, add durability to the quilt, and give it a finished look. Binding can be made from the same fabric as the quilt top or a contrasting fabric to add interest.
Binding is typically sewn on by machine to the front of the quilt and then folded over to the back and hand-stitched in place. The width of the binding can vary, but it is usually between 1.5 inches and 2.5 inches.
Types of Binding
There are several types of binding that can be used for a quilt. The most common types are single-fold binding, double-fold binding, and bias binding.
Single-fold binding: Single-fold binding is made by folding the fabric in half lengthwise and pressing it. It is then sewn onto the quilt with a quarter-inch seam allowance and folded over to the back and hand-stitched in place.
Double-fold binding: Double-fold binding is made by folding the fabric in half lengthwise and then folding it in half again. It is then sewn onto the quilt with a quarter-inch seam allowance and folded over to the back and hand-stitched in place.
Bias binding: Bias binding is made by cutting the fabric on the bias, which means at a 45-degree angle to the selvage edge. This type of binding is more flexible than straight-grain binding and is ideal for quilts with curved edges.
Binding can also be made from pre-made bias tape or ribbon, which can save time and add a decorative touch to the quilt.
Understanding the different types of binding and their purposes is important for any quilter. By choosing the right type of binding, a quilter can ensure that their quilt is durable, has a finished look, and is protected from fraying.
Materials Needed
Fabric Selection
When it comes to selecting fabric for the binding of a quilt, there are a few things to consider. First, choose a fabric that complements the colors and patterns in the quilt top. It is also important to choose a fabric that is durable and can withstand wear and tear. Cotton is a popular choice for binding fabric due to its durability and easy care.
Measuring Tools
Accurate measurements are essential when calculating the amount of binding fabric needed for a quilt. A measuring tape is the most common tool used for measuring the length and width of the quilt. A clear quilting ruler is also helpful for measuring and marking the fabric for cutting.
Cutting Instruments
To cut the binding fabric accurately, a rotary cutter is recommended. A rotary cutter is a handheld tool that uses a circular blade to cut through multiple layers of fabric at once. A cutting mat is also necessary to protect the surface underneath and ensure clean cuts. It is also helpful to have a pair of sharp fabric scissors on hand for trimming any stray threads or uneven edges.
By having these materials on hand, calculating and cutting binding fabric for a quilt can be a simple and enjoyable process.
Calculating Binding Length
Measuring Your Quilt
Before calculating the binding length, you need to measure your quilt. Measure the width and length of your quilt in inches and add the two numbers together. This will give you the total perimeter of your quilt.
Determining Total Length
To determine the total length of binding needed for your quilt, add 10 inches to the total perimeter of your quilt. This extra length is required to join the ends of the binding tape on the quilt and to join the binding strips.
Next, divide the total length by 40. This will give you the number of strips of binding you need. Round up to the nearest whole number to ensure you have enough binding strips.
Accounting for Mitered Corners
If your quilt has mitered corners, you will need to add extra length to the total binding length. The amount of extra length needed will depend on the width of your binding strips and the angle of your mitered corners.
To calculate the extra length needed for mitered corners, multiply the width of your binding strips by the number of mitered corners. Next, multiply this number by the length of the diagonal of your mitered corner. Finally, add this number to the total length of binding needed for your quilt.
In summary, calculating the length of binding needed for your quilt is a straightforward process. Measure the width and length of your quilt, add 10 inches to the total perimeter, and divide by 40 to determine the number of binding strips needed. If your quilt has mitered corners, be sure to add extra length to account for them.
Cutting the Binding Strips
Width of Strips
The width of the binding strips is a personal preference, but it is recommended to use 2 1/2 inch strips for most quilts. However, wider or narrower strips can be used depending on the desired look and feel of the finished quilt.
Number of Strips
To determine the number of strips needed, divide the total length of the binding needed by the width of the strips. For example, if 140 inches of binding is needed for a quilt and 2 1/2 inch strips are being used, divide 140 by 2.5 to get 56 strips. Keep in mind that it is always better to have extra strips, as piecing together additional strips can be done if needed.
It is recommended to cut the binding strips on the bias to prevent the binding from stretching out of shape. To do this, cut the strips at a 45-degree angle to the selvage edge of the fabric. This will also allow the binding to curve around the edges of the quilt more easily.
Once the strips are cut, they can be joined together using diagonal seams to create one long continuous strip. It is important to trim the excess fabric and press the seam allowances open to reduce bulk. Finally, the binding strip can be pressed in half lengthwise, creating a clean and finished edge.
Joining the Binding Strips
When it comes to binding a quilt, joining the binding strips is an important step that requires careful attention. There are two main methods for joining the binding strips: sewing the ends together and pressing seams open.
Sewing Ends Together
To sew the ends of the binding strips together, place the two ends right sides together at a 90-degree angle. Sew a diagonal line from the top left corner to the bottom right corner, making sure to backstitch at the beginning and end. Trim the excess fabric, leaving a 1/4 inch seam allowance, and press the seam open.
Pressing Seams
After sewing the binding strips together, it's important to press the seams to ensure a smooth and flat binding. To do this, place the binding strip on the ironing board with the seam facing up. Use a hot iron to press the seam open, making sure to avoid stretching or distorting the fabric.
By following these simple steps, you can join your binding strips with ease and achieve a professional-looking finish for your quilt.
Attaching Binding to the Quilt
Once the binding strips are cut and sewn together, it's time to attach them to the quilt. There are two ways to attach the binding to the quilt: machine stitching and hand stitching.
Machine Stitching
Machine stitching is a faster and easier way to attach the binding to the quilt. Here are the steps to follow:
- Starting from the middle of one side, leave a 6-8 inch "tail" of binding unfolded.
- Begin stitching with a 1/4 inch seam, aligning the raw edge of the binding with the edge of the quilt.
- Stop 1/4 inch from the first corner and backstitch.
- Fold the binding up at a 45-degree angle, creating a diagonal fold that goes from the corner of the quilt to the edge of the binding.
- Fold the binding back down over itself, aligning the top edge of the binding with the top edge of the quilt.
- Start stitching again at the edge of the quilt, continuing to the next corner and repeating steps 3-5 until all corners are mitered and the binding is attached to the quilt.
- Once the binding is attached to the quilt, fold it over to the back of the quilt and secure it with clips or pins.
- Stitch in the ditch along the seam between the binding and the quilt to secure the binding to the quilt.
Hand Stitching
Hand stitching is a traditional way to attach the binding to the quilt and creates a more polished look. Here are the steps to follow:
- Starting from the middle of one side, leave a 6-8 inch "tail" of binding unfolded.
- Begin stitching with a needle and thread, hiding the knot inside the folded binding.
- Take a small stitch through the quilt and then bring the needle up through the fold of the binding.
- Take a small stitch through the fold of the binding and then bring the needle back down through the quilt.
- Continue stitching in this manner, taking small stitches through the quilt and the binding until you reach the corner.
- Miter the corner by folding the binding up at a 45-degree angle and then folding it back down over itself.
- Continue stitching along the next side, repeating steps 3-6 until all corners are mitered and the binding is attached to the quilt.
- Once the binding is attached to the quilt, fold it over to the back of the quilt and secure it with clips or pins.
- Use a blind stitch to hand stitch the binding to the back of the quilt, hiding the stitches as much as possible.
Finishing Touches
Trimming Excess
Once the binding is sewn onto the quilt, it is time to trim the excess fabric. Use a rotary cutter and ruler to trim the binding to 1/4 inch beyond the seam line. This will ensure that the binding lays flat and does not bunch up or pucker.
Final Pressing
After trimming the excess fabric, it is time to give the quilt a final pressing. Lay the quilt on a flat surface and press the binding away from the quilt top using a hot iron. Be careful not to stretch or distort the quilt top or binding while pressing. Once the binding is pressed, the quilt is ready to be displayed or used.
By following these simple steps, anyone can calculate and sew binding onto a quilt with ease. With a little practice and patience, anyone can create a beautiful and professional-looking finished quilt.
