Those are great tips!! I have never saved over a piece *knock on wood*, but I can see how making the copy of the kit would be a good safety net while scrapping.
Normally I save as I go, this was only 4 pieces so I hadn't gotten to the moment where I felt I "needed to save" yet... it was just a hard 4 pieces to get lined up juuuuuuuuuuuuust right. Soooo, I have put the idea in the back of my head and have moved on to a different page... because I am not attempting that again any time soon. lol
