Hi. I'm sending you some good advice here: when you go to the store (in April?) get some Invisigrip to stick onto the bottoms of all your cutting rulers and templates. The @$%&)*(&^% acrylic and/or metal rulers and templates slip all the time if you do not have some non-slip stuff stuck onto their bottoms; even the ones that are "designed not to slip" DO slip. When you are cutting anything and especially a narrow strip of fabric, it is infuriating when the ruler slips. You can almost secure a wide ruler or template with your other hand and arm, but a narrow ruler is impossible to control properly without "gripper" on the bottom. I used to have the little vinyl circles stuck onto the bottoms of my rulers and templates but they are too fat and allow the rotary cutter to get underneath the ruler, causing more crooked cutting! So, I pulled off all the vinyl bumps and replaced them with Invisigrip. It's not inexpensive, so if you can use coupons or get it on sale would be good.
