I think everyone feels this way with there first quilt. I'm sure it will turn out better than you think. I always want my quilts to be perfect and my DH is the worst critic. He is always checking my points (I know that is really a good thing-hee hee). Remember this is "supposed" be fun and relaxing!!
Love your avatar - cool blue eye, is it a paint? I've had 9 horses-no blue eyes (at least my huskies do)
