Take a look at these cross stitch necklaces made by starrley which are featured on her Stitching blog, Stitching Shop. From the artist herself:

“This is a handmade, by me, Pikachu cross stitched necklace. It is on an 18″ black velvet cord. It is stitched on plastic canvas, so it is very durable. The back is covered in soft felt. Pikachu measures 2″ tall, from top of the ear to bottom of the head.
Cute, fun, and awesome! Take your adorable Pokemon everywhere you go.
Interested in having a different Pokemon on a necklace? Send me a message and we’ll make it happen.”
