How to Make Bias Tape
Where is elastic when you need it?! Now that face masks are in high demand, many of their component parts are in short supply. In particular, it is very hard to find the elastic customarily used for ear loops.
No elastic means that mask makers—already a creative group—have had to get even more creative. Makers are now making ear loops and ties with ribbon, hair ties, strips of stretchy knit material and bias tape. Of these options, homemade bias tape is the least expensive and easiest to get your hands on; as long as you have fabric, you can make bias tape.

Traditional bias tape is made from cutting strips of fabric on the bias and sewing them together. However, for mask-making purposes, bias tape is made more simply by cutting fabric strips parallel to the grain. Making your own bias tape is not difficult and you can make bias tape without any special tools. However, it is easier and a bit faster to make bias tape with a bias tape maker tool.
As soon as they became aware that our makers could use bias tape maker tools, 3D printer volunteers Greg Bertenshaw and Steven Toms downloaded printable files for the tools from the Internet. They loaded the files into their printers and printed several different models of bias tape makers in a rainbow of colors. These tools are now available for volunteer makers.
