More felted sweaters projects

I'm still in my felted jumpers/sweaters phase and yesterday I made this 'trivet' (or table topper). Cool, hey? Here is a view from above:



Much as I like them, I don't really need more than one of these things, so I've added it to my Etsy shop - you can find it here. I also made a smaller version of the Baby Blocks (or Tumbling Blocks) trivet I showed here a week ago:



I've added that one to the shop as well - I think it would make a great mouse pad!
And here is another one - this block is known as Card Tricks. It's a small one, I think I will keep it and use it as a coaster:



I've still got a pile of felt, so I'm not done yet! Any suggestions for quilt blocks I could make with felted shapes?
