Hi Cordelia:
I love your embroideried bear. It looks really nice on your quilt. I was a beginner when I did this quilt, too. My sister helped me every step of the way, or I would never have known what to do. :D If I remember correctly, once you attach the sashing, the blocks work out to be about 16". Each block has different sizes of sashing. That's how they come out to be the same size. Hope that makes sense. I don't know where my directions are off-hand, but I still have them and will be glad to help you out any way I can. Just let me know.
Debbie
