This is an excellent question. Hmmm I know my personal challenge myself quilt this year will be a Bargello. Now a skill I'd like to work on.....I will go with making panel quilts fun for myself. I have a bunch of panels but my mind goes blank sometimes for days when working with them. I love them and the look I get when the quilt is done. However I spend a lot of time frog stitching to get what I want.
