As the more observant of you may notice, they are the same style as the little bags I wrote a tutorial on at the beginning of September. See here if you missed it.
Some closer photos of the monster bags:
I've used Bondaweb to stick the monster's pieces together and then either used a close zig-zag stitch or running stitch to outline each of them. I plan on making more in different colours with different monsters, but as the market is tomorrow morning, I think I'll have to just stick to the 2 I've already made. Fingers crossed they'll sell, will update you tomorrow to let you know.
