Here is another excellent tutorial for back-basting. Go to www.appleblossomquilts.com/tips. She has the best tutorial that I have found on back basting. She also tells how to line a patch so the background won't show through. And how to use Glad's Press N' Seal for dark backgrounds. She came to our guild and taught a class with these techniques and I learned so much, even though I had been doing back-basting for several years. I use a Sanford Pigma pen(usually brown) to mark the lines on the back and I hope that they go through to the front a little too, as I can see the line to follow. If the lines don't show enough on the front, I sometimes go over them again on the front, sure makes it easy to needle turn and follow the pattern exactly. Hope you like the tutorials, they are excellent.
