|I like to iron my pattern pieces so they are nice and flat. That way, I'm more accurate when cutting my fabric. However, I don't have a workroom where I can let my pattern pieces lay out during the course of the project which could be days or even weeks. I also have cats that like to "help" me by listening to the paper crinkle as they play in it.
My solution was to to take a binder clip like you can get at Office Max, flip the handles back so they can be sueezed to open the clip, run an 8" piece of string through the two handles, and tie the string ends together to form a loop. What you get is a binder clip on a loop. Clip your pattern pieces on and throw the loop it over a hook or tack the loop to a cork board. No more wrinkled pattern pieces until your done with your project!
