I'm finishing the same quilt from a class as well. Unfortunately, I lost my mind, and decided to make a queen(96x96). What a nightmare to baste, and because the basting on my floor was so difficult, the quilt is bunching up in certain areas as I quilt. Not to mention the bulk in my 9"harp. It's frustrating, but I'm just going to finish and get it out of the sewing room.
Yours looks great. How do you plan to quilt it? I have just stiched in the ditch around all the stars and about half the blocks-I have the other half to go. Then the borders. I should have just meandered and been done-it would have been much easier.
