Tuesday Tutorials: How to Make Continuous Bias | McCall’s Quilting Blog
Bias-cut fabric strips are super useful in quilt making. Curving vines in appliqué quilt patterns wouldn’t exist without them. And bias-cut quilt binding strips are a must for quilts with curved edges, like scallops, and a cute plus for certain binding fabrics like stripes. But most applications take a lot of bias-cut strips, and cutting on the bias can be tricky since the bias grain of fabric is very stretchy. So what’s a quilter to do?
There is a very cool method for making as long a bias-cut strip as you need, in 1 continuous strip. I’m not exaggerating when I say…it’s almost like magic! If you haven’t tried it yet, grab a square of fabric, fabric marker, rotary cutter, and a nice long ruler and watch our free how-to video by editor-in-chief emeritus Beth Hayes. You can also refer to the instructions below, but you definitely want to watch the video to get the hang of this technique.
Step-by-Step Instructions
Step 1. Determine how many inches of bias-cut strip you need. If using for quilt binding, allow 10″ extra for turning corners and the closure. The equation is: [(height of quilt + width of quilt) x 2] + 10. Refer to chart to find the size fabric square needed.
Size Fabric Square to Cut | ||||
Length Needed |
1½˝-Wide Bias Strip |
2˝-Wide Bias Strip |
2½˝-Wide Bias Strip |
3˝-Wide Bias Strip |
110˝ | 14˝ square | 16˝ square | 18˝ square | 20˝ square |
220˝ | 19˝ square | 23˝ square | 26˝ square | 28˝ square |
340˝ | 23˝ square | 28˝ square | 32˝ square | 35˝ square |
480˝ | 28˝ square | 33″ square | 37˝ square | 40˝ square |
Step 2. Cut the square in half diagonally (Diagram I).
Step 3. With right sides together, sew the triangles together with a 1/4″ seam and press open (Diagram II).
On fabric wrong side long edges, draw lines to make strips of your chosen width. Use a clear acrylic rotary ruler and a pencil or fine-point permanent pen to draw the lines.
Step 4. Bring the short diagonal edges together, forming a tube (Diagram III). Offset the drawn lines by one strip. With right sides together, match lines with pins at the 1/4″ seamline and stitch seam; press open.
With scissors, cut along continuously drawn line.
That’s all there is to it! Presto change-o, you have yards of continuous bias-cut strip.
