Jen at Shabby Fabrics.com gives a good demo on making a baby receiving blanket with self binding. I'm making some for a new g niece. Jen gave fabric amounts, but did not tell you that the top needs to be 30"x30" and the backing 40"x40" (only a square will work the way she does her blanket,) she only stated that the top was 30" and the back 40". Birthing and envelope quilts are the same in my opinion. Zozee your answer is the best yet. Thanks for the morning giggle.
