I am new at doing patterns and currently have a project that is 6.43" W x 7.36" H (85 x 99 stitch) on 14ct Aida. How much additional material do I need to frame this when completed. I guess what I am asking is how much material do you add to the edges once you know your design area.
I would also leave about 2 inches of space. Perhaps a bit more or less depending on the size of the project. Sometimes one can be leave too much which can get in the way of a good framing job, which happened to me once.
