That brings up another problem. I went to my local WalMart and they don't know what a color catcher is. They didn't know what freezer paper was either. My husband found me some freezer paper at Zehrs Grocery. I don't know if it is the right stuff. It's by Reynolds and says its plastic coated. I did not check their for color catchers yet. I also don't know if is makes a difference on unwashed fabric when I use my disappearing marking pens.
