Most of my quilting rulers are from Creative Grids, and have little nonslip dots on the back of them, to make them stable when cutting out fabric shapes.
I hadn't actually appreciated that as much as I should have, till I used my EZ Triangle ruler. This is a great ruler for making HSTs and flying geese etc, but occasionally it slips a bit and the shapes aren't completely accurate. Now, I need all the help I can get with accuracy, so if my shapes haven't been cut accurately, I'm on a loser! I was sure there must be a solution to this problem, and found that there are indeed products you can buy to do this job. But I didn't want a product I can buy, I wanted an instant fix! And then I found a tip using surgical tape. I have micropore tape in my first aid box, so wondered if that would do the job.
And the answer is yes! I put two pieces on there as you flip the ruler, and it's fabulous! Now here's hoping it'll make my quilts more accurate (don't hold your breath!)
