What to do with a tangle of threads?

I found a huge tangle of threads in the back of my car after the most recent Region 1 Regional day. As these are my favourite colours I didn't want to throw them away.

Here they are on a Little Gem, called " The Big Tangle" . The hearts are an experiment with water-soluble stabiliser, sewn straight on to the stabiliser using a sprung embroidery hoop and then sewn on to this piece with invisible thread. The little hands were made with polymer clay and a push-out mould - a bit fiddly but good fun.
