I decided I would feel a whole lot more ready to meet the challenge of this swap if I had a design wall that wasn't the floor so off I trundled to Bunnings to get some tape and hey presto, job done!
Basically to make this quilt I built some blocks then spent ages trying to figure out how to get them to go together - both in a design sense and in a construction sense. You'll see that I couldn't resist putting in one of my Starburst blocks :-)
I'm going to put it away now for a few days and see if it is 'finished' when I look at it again. Hopefully the answer is yes!
