|I've started using pastel tissue paper - the kind you have on hand for gifts- for tracing some pattern pieces. Some patterns provide separate pattern pieces for interfacing, and sometimes it's just easier to make an interfacing pattern. I now try to trace these special pieces onto the pastel paper, making it easier and faster to lay out a pattern for cutting. The colored paper is my clue that I shouldn't cut the piece out of the fashion fabric. (Yeah, I've done it....) It would also work for pattern pieces that should be cut out of contrasting fabric, or for lining pieces.
