All that's needed for their creation are some clothespins and glue. (I use quick drying craft glue but a glue gun or other adhesive would probably work fine as well.)
I started by taking all the clothespins apart.
(Depending on the specific size and shape of the pins used, the number needed for a complete circle will vary from about 22 to 30.)
(Ed. Note Dec. 2013: I just found a great use for the leftover metal bits! Check it out here.)
I then glued the two separated pieces back together back to back.
After they had dried, I glued the smaller ends together to form the starburst shape.
To make an even, smooth inside edge, it helped to use a form to push the pins against. For this size, I found the perfect sized lid as a kind of mold.
They can be decorated or, of course, left in their natural state.
The round starbursts I'll probably hang in a window but Naiya and I also made and decorated a half circle to use in pretend play as a setting sun. So sparkly!
As an afterthought...
When these new creations were sitting around the kitchen waiting for some inspired use, I realized they'd also make for natural, sort of retro coasters and trivets!
