A ceramic tile under the pincushion adds weight so it sits securely in place (found at Lowe’s, Home Depot and hardware stores). Velcro holds the pincushion (7″ x 3 3/4″) and you can easily detach it.
The thread catcher basket measures 5 3/4 inches tall by 5 1/2 inches across and has an optional tab for your scissors.
The designer, Curry Bungalow, has three versions of this pattern available, each with a different pincushion design. You can also purchase supply kits containing the interfacing and such needed to complete the project. There are even finished thread catchers available (sometimes).
