I had to piece the backing. 3 big giant "strips". Well, I was putting said backing on the frame yesterday (First time I've ever used the frame too... so glad I did, because I would have missed this) and saw that I sewed a tiny bit of flap into the seam. Seriously, it would not have been noticed if I'd basted it!! And once it'd been quilted, it would have looked like a regular ole pucker. So I picked that seam out at that spot and I used Iron-on seam stuff to patch it with a matching scrap! You know, I forgot to check that when I took it off the frame yesterday.... Oh well, I'm sure it will be ok!!
