I did this pin keeper for a swap. I wanted to create a different thing for my swap partner. I thought to applique a little crocheted hat on the front side should be a nice idea. I guess, its red ribbon and crystal bead made a nice contrast with the fabric. I used a thin layer of fiber between fabrics, it gave a good puffiness. At the inside, I used a green fabric, it is like a velvet. As far as I remember it was a swap goodie from Japan. At last, I stitched edges with blanket stitch. I used variegated green cotton thread, it also made a good harmony with the fabric.
