One thing I would suggest: The instructions don't say so, but I wished I had sewn in two loops to hang it. I like to hang my quilts to let them air out before packing them away. As soon as I can remember to pickup some grossgrain, I'll add them.

Adjusting the pattern to your needs is really easy.
I can pack my quilt (no alpine option) in a 15" long by 6" diameter stuff sack. It will stuff smaller than that when I put it in the pack.
