Don't give up! It takes a lot of practice to feel comfortable doing it. I've gone thru many practice sandwiches before attempting on a "real" quilt. I think stippling is one of the hardest things to do well. I find that I do pretty good with loops, curliques, wavy lines. I can do straight lines now if I turn it so it is forward/backward. I don't do well with diagonal lines. When you practice, notice which types you feel most comfortable with and do lots of those. Once you get the hang of that, move on to other things. When I first started, I couldn't follow a pattern well at all. I'm much better now. Keep trying! And relax, it's supposed to be enjoyable! :)
