I have a big cork collection so I had fun sewing half corks to everyone's block. Some I was able to cut in half with a cleaver, but I discovered a small hack saw worked best on the denser ones.
Here is my blank block ready to send off for the others to work on. I see I forgot to take a picture of my finished block, so I must do that before I can finish this post.
This is the finished block. Isn't it great? All of the blocks came out wonderfull and I'd not hesitate to sign up for another round.
