I was hoping to make a drunkard's path quilt soon, but I want to get a ruler for cutting the curved pieces. There are so many specialty rulers out there for this that I don't really know which one is best. I would like one that will make multiple sized blocks, if possible. Have you tried any? Which one is the best for someone making a quilt with curved seams fior the first time? Are there any good ones that give you more than one size finished block?
