What a fun quilt-to-be! I must comment about the buttons though.
I made my sister a lovely quilt. The fabrics were all floral. Instead of quilting or tying the quilt I tacked it with cute flower buttons. My dear sister called and told me she was removing the buttons after she'd sat on them the second or third time. They were just plain uncomfortable and ruined the coziness as far as she was concerned. I'm still waiting for her to bring the quilt back for me to quilt it. Meanwhile she's always bragging about curling up with her quilt! No more buttons on quilts unless they're wall hangings.
