I also have done an Elizabeth Hartman quilt, the dinosaurs and someone mentioned to me when she heard I was making one......I thought you didn't care for tiny pieces and boy, her quilts seem to have a lot of them as I noticed yours does too. Anyway, I plugged along and now I'm not afraid of tiny pieces but I won't jump into another pattern just for that reason. Just keep plugging along and you'll get it done and be so happy with the outcome. Good luck!!!!
It's when you have to work with tiny pieces that starching the fabric beforehand helps tremendously I find.
