Hi Marylou,
I recently finished a quilt that measures 115 x 115 (I'm using it as a bedspread on my king size bed). I also used this method for quilting (didn't see the program you watched, just figured it out on my own) and it worked out well. Will send pics if you wish !! I just joined this forum today. I think I'm going to like it :lol: I too was doing a search on reversible quilts. Think I will try the cotton method of "one way" and "highway" stitching for assembly on my next project.
