I had a small LA when I first started, and the biggest panto I could use was 5-6". Be warned, as you get to the end of the quilt, things get pretty tight when you need to roll the quilt because you have so little room. So I would say to maybe stick with a 5-6" one and you'll be happy...or you can even go a little smaller if you like. Good luck, show us some pics when you get it done.
