She thought this was so cool, especially since she's done cross-stitch on fabric. She worked most of the morning on it and I even caught her doing some math to figure out the placement of some "stitches."
edited to add: I wasn't very clear about the mechanics of this project. We printed graph paper off the computer (5 squares to the inch) and she made the design lightly in pencil. Then she traced over all the x's with markers.
