See the frog skeleton on the pocket? I love the way that turned out! It's a reversal of my embedded object technique. See, I print the image on oaktag, use WonderUnder to fuse the oaktag to a thick piece of felt, then cut away just the printed skeleton with my exacto knife (of course, it gets tricky when you have unattached inner parts, like at the eyes, so I lightly glue a netting underneath the felt, and glue those bits back in..). Anyhow, I create a negative image on the oaktag-felt, shove that under the cloth, and then sew down the empty lines, so it looks (sort of) like it's carved into the fabric.
I used discharge paste to create the button images , then sewed down the images to make them indented. The tiny twig circles are lobster traps:
