I think I am just frustrated. Right now I am trying to figure out the layout. I originally forgot seam allowance when I cut 8" squares. Then I learned about 'squaring up' the blocks so now I have 7.75" and 7.25" squares. I'm not sure if I should use a 1/4" or 1/2" seam. And the quilt back I bought might be 100% polyester which I have been reading is not a good material for the back. I'm sure this group will be very helpful as I move between steps.
