Personally NOT for me. I Hate the 2-inch squares and always move them up to at least a 3-inch size. I make the main design for the center and then block it off with the main-minor colors to give it a square section.
did you mean this post for this thread MaryKa? the pieces in a mosaic this small (11x!4" I think) are 3/8" square or trimmed smaller. There is nothing stitched together until you get to the border.
If you are doing a big mosaic we'd love to see a photo!
