Washing machine samples

I have been expeimenting with the washing machine a bit. To make these I cut a whole lot of long pieces of all these different types of wool, then tied some in bundles and left some single. I put some with their ends in laundry bags and some just in the washing machine. I put them through a cotton sturdy warm wash, and they felted into these fantastic sea erchin shapes, and bulby yarns. I think these could be great used as a decorative part of gaments, like on the shoulder of a dress or on a waistband or something like that?
