The actual design on the stencil is 9" x 4 3/4" but it's listed as 9" x 9" because you pivot the stencil to transfer the other half which is overlayed by 1/4".

It's for larger blocks without having to buy a larger stencil.

These unique stencils are transferred with a Quilt Pounce Pad™, and because the material is a nylon mesh open only on the design lines, the powder goes right through to the quilt top!

There are no breaks or bridges to fill in, no mess, and it’s easy, fun, and effortless to transfer beautiful designs onto your quilt tops.
