Print pattern actual size on A4 paper (don't click the fit in print area box) Embellish with nice pom pom edging or embroidery. Good fabrics are denim, corduroy, linen and stiff cottons. Stretchy fabrics will not work properly, it needs quite a robust weight of fabric to hold it's shape. You can use velcro or snaps to fasten.
If you want to use this pattern for personal use please feel free and enjoy, but don't use it for selling without crediting me. Many thanks.
