I agree with the other ladies. This isn't bad for a first. I too prefer applique because my piecing skills are lacking. However, after getting Harriet Hargrave's "Quilting Academy" books and following her techniques, I have improved considerably. I believe it's either her Junior or Senior book that deals with triangles. The Sally Collins book is also great for learning accurate piecing, but I find Harriet's book easier. Harriet gives you projects to practice on. I now measure each piece that I sew to make sure it's accurate. It takes more time, but a lot less frustrating than to have a finished block you are unhappy with. Keep at it. The more you do, the better you will become.
Having said all that, I still prefer applique.
