I too have used the twister ruler for a Christmas theme quilt, but mine wasn't of a tree. I agree with you that it is a lot of work assembling, cutting, and reassembling with a lot of waste. I did use the smaller ruler for some of the waste to make small twisters. Seeing your pretty quilt makes me want to do a wall size quilt. I have seen the cute Halloween theme, pumpkins, wall quilts done with the twister. I might give that a try. Although, it may not get done in time for this year's Halloween.
