This is a fabulous non-slip tape, 5mm wide, which you can stick to the back of templates, large and small, to help prevent slipping on fabric. I use this tape constantly on the back of small templates so that I can easily trace around them for fussy cutting without the template moving.
It can also be applied to larger templates and rulers to stop slipping when you are using your rotary cutter. This is a great tool to have in your sewing kit! The roll contains tape 5mm wide x 9 metres long.
