I read up about the easy sandwich half square triangle approach on About.com:Quilting, a site that just keeps on giving in terms of patterns, blocks and methods and used that. The easy sandwich method works well for me because it keeps those stretchy bias seams from moving about too much.
The leaf fabric was a $4 a metre hard to love quilting cotton that was heavily reduced at Spotlight due, let’s be honest, to its ugliness. The shop assistant and I agreed that it was ugly but she also said it might turn out to be the best part of my quilt. I think she was kind of right. Cut up and with a green background, it turns from ugly into quite OK.
