This is the durable leather Ugly Thimble invented by Cathy's Creations. You can custom fit this thimble to your own finger! It's also flexible and feels better than a hard metal thimble. 
 
The Ugly thimble kit comes with all the parts of the thimble.  All you need to add is washable school glue. I use Elmer's purple washable school glue sticks.
