OMG!! I hate that stuff... I bought a can of temp basteing spray and that is the darnest stuff to get off.... I use tweezers to hold small items wheile I spray,, and I have usd acetone, alchol, goo gone, WD 40 and LOTS of elbow grease....
I freq will trace a pattern onto freezer paper and them iron it on to the fabric.... works great once..... after than I"m back to pinning.. but I usually dont make too many clothes these days.
