The slightly wonky perspective is deceiving. It did end up a rectangle with straight sides, which was reassuring since I didn't trim the batik strips I started with, and they were slightly different widths...woops. Anyway, all's well that ends well.
First there were the skipped stitches on the middle few rows.
Tension problem? Going too fast with a walking foot? I don't have enough experience to know. I sewed the rows down, going very very very slowly. Didn't have the patience to unpick and re-sew. (Sigh.) But it doesn't look too bad, for a first try at all this. Ahem. And the butterflies are doing their job of distracting.
I felt better, so I got out the binding I had cut out and sewn together over the weekend. I sewed it together just like binding for clothing (I thought) except I managed to somehow sew one strip to the front of one, then that strip to the back of the next, alternating back-front-back-front, the entire way.
(This is with it folded to show the alternating seam problems.)
So......I must cut it all apart and re-sew. What's that line about falling off a horse?
