Alrighty then - just found out grandbaby is a boy, due in January. They live in a moderate climate, so I'm going without batting. Sounds like basting spray and my silicone slider will be helpful, have gotten both out and am ready to go. I can't believe i didn't think about pre-shrinking the flannel top - thanks for the reminder. I'm anxious to see how the definition turns out. Daughter wants fabric from her wedding dress for the binding, so will go with a fairly wide piece all around. I was waiting to find out what we're getting to decide on a ruffle edge, but I'll just go with flat for him. No ruffles for Junior! I'll post pictures when it's finished.
Thanks so much for all the helpful comments and suggestions.
