My new project. Haven't quilted in a while, but I finally cleaned up my junk room and now Ganny has her Toy room back. So I'm finishing an unfinished project. My Aunt who taught me to quilt gave me these six panels, so I crossed stitched them probably 5 years ago and never knew what to do with them. So now that I have my room back, I decided to do something with it. However I have a question. I traced the designs using pencil (very lightly) cause that's how my Aunt always did them. The question is , what is the best thing to use to remove them once I've finished the quilt. Since it's all hand done I don't want to lighten up the threads.
