Since then, I have taken apart the four patch units so that the ones I had already done were only in pairs. It was going to be unnecessarily difficult to sew the four patch units together, so I decided to keep the pairs together and then join them as rows first (just like the directions say, dang it!).
So, today, I sewed two rows of 14. Here's a picture of the first one:
So, you can picture me sewing the two rows together tomorrow. Eventually I will have to decide whether or not I want to leave the edges zigzaggy, but I think I'll wait to see how it looks that way.
