The directions to the guild members were to make one or more blocks using striped prints or by making stripes of their own. The blocks were to measure 10.5 inches square or 5.5" x 10.5" when they were turned in.
I immediately set about using my 15 Minutes to make stripe blocks. The first day my stripes were slightly less than 5" wide although I did manage to get the necessary length. So the next time I just added long strips to either side of my narrow block. At the same time I was able to piece together one of the half-blocks.
And now I'm on my way to having a stripey quilt of my very own! Fun!
