I've been making some hand-sewn and embroidered felt cat brooches; here is one that is white, with green eyes and brown markings.
The cat below is gray with blue and white.
They both have a pin clasp sewn onto the back.
Below is a different gray one . . .
Oh, one more thing . . . these can be found in my Etsy fabric art shop, Fuzzlemania, along with an assortment of other brooches and some felt magnets.
