I've been doing a little experimenting, and over the past few days I've made a pillow and set of magnets.
The largest of the magnets is about 3 1/4" X 2 1/4". Materials are huipil fabric, fleece, embroidery thread, and magnets (attached with super glue). If you interested, the set of four is $14 plus $1 shipping. SOLD
The throw pillow I made is about 8" X 10". Materials are hot pink and light purple fleece, huipil fabric, embroidery thread, and polyfill. The design is kind of "planetary." It's $25 plus $2 shipping.
