The whole project is 29"x29". Each block is about 11x11. I say "about," because one of the lessons I learned on this project is to be much more precise about where my seam basting lines are placed!
To quilt, I stitched in the ditch of each square. Then I added beads and buttons as an additional way to secure the large squares to the backing.
The little white buttons in around the watch are attached with French knots.
