These first two are washi paper mounted on cardstock and then cut out as waves (along with some plain cardstock as well). The orca is two layers of metallic cardstock.
I wanted to find a way to use all the little bits of leftover cardstock and got in my head to try weaving a card. This is just a little more fiddly than a potholder, as it is challenging to keep the things lined up and not going wonky. But I like it.
