Thread catcher. instead of the usual 4 inch tile, we are using a 3 x 6 subway tile as the base for the pincushion. It is made lattice style (think pie crust...) with woven strips put together to form the top of the pincushion. It also includes an emery pad, the center of the flower, for sharpening needles. The pincushion attaches to the tile with Velcro so it can be detached if desired.
