I have the red clips. For those who may not have seen them --they lie flat on the clear side and have 1/4" and 1/2" markings on it and the red side is rounded for bulky seams or binding. These clips were made for fabric and they really hold even slippery fabrics very well and they hold vinyl better than paper clips. I like them because (1) my GD likes to pull pins out of projects into the carpet which DH finds with his bare feet, (2) my cat likes to pull pins out of my pincusions and tries to eat them, and (3) I tend to prick my fingers on a regular basis. I like them a lot.
