Last week in my sewing technique series I showed you how to cut and sew bias tape. So today I thought I would share how to make bias binding with a bias binding maker as lots of my sewing tutorials of late feature bias binding from edging the coin purse to finishing off the ends of the pretty lace zip pencil case.
Bias binding, or bias tape, is a narrow length of fabric cut on the "bias", meaning that it has been cut at a 45º angle to the grainline or selvedges. When woven fabric is cut on the bias, it has greater flexibility and stretch than fabric cut on the straight grain. This makes bias binding ideal for finishing off a rounded edge, trimming quilts and adding a decorative touch.
You can of course, buy pre-made bias binding, but this will be limited to the colours and prints you can find in the shops. If you do it yourself, you can make it from any fabric you happen to be using, allowing your binding to perfectly match (or perfectly clash!) your project.
The edges are folded under once for single fold tape, and twice for double fold tape. Single fold bias tape is great for surface embellishment. Double fold bias tape is used to bind the edges of quilts and other craft or sewing projects.
Making bias tape couldn’t be easier. You only need a few simple tools: an iron, ironing board, and bias tape maker. The Bias Tape Maker is a tool through which bias-cut fabric strips are fed to make a single fold tape. It’s like having a third hand. You don’t have to use one, but it makes life easier!
Bias tape makers come in many sizes. The size of the bias tape maker refers to the width of the binding before pressing it in half. For example, if you want to make 9mm binding then you would purchase a 18mm Bias tape maker.
To figure width for a double fold, start with the seam allowance. This must be doubled because the fabric is folded in half. Then, take the finished binding depth and multiply that by four. See illustration below for clarity...
