what to do with colouring in ?

I end up with heaps of colouring in pages some are treasured in a book, but others end up getting recycled I want to come up with some creative things to do with these pictures. Idea 1, ice cream stick puppets
combine one paddle pop stick some sticky tape and a cut out colouring in picture voila. We took ours into the sandpit the boys enjoyed burying, pretend watering, and feeding them bits of leaves. Not to mention the fire engines rescued the birds and bugs from multiple fires.
