I know this is an old thread, but I just had to add my two cents' worth in case others are stumbling across this discussion in their research for their own baby blankets. I have done several baby quilts with Minky plush fabric as backing, a very thin minimal shrink batting in between, and a cotton quilt top, and I do use prepackaged satin binding on the edges. Moms and babies love these special quilt/blankets. They are soft, warm, snuggly, and it's a great combination of textures. The quilting is very minimal, just enough to hold the layers together. I do baste around the edges with my walking foot, and then I serge the edges for a clean, durable finish, adjusting my dual feed if needed to avoid a wavy edge (since Minky does stretch in one direction). The satin binding goes on easily, just pin in place and sew along the edge with a triple zigzag and a walking foot, if you have one, to keep things feeding evenly. It's VERY durable and, worst case scenario, if the satin binding came loose my raw edges are protected by the overcast serger stitches underneath -- worn out satin binding could be easily replaced. So I hope that others considering satin binding for a baby quilt are not too discouraged to try it themselves!
