Me and Ds did it. Just got some cheapo sugar paper from his pile, I did a very random squirly design in PVA and he chucked glitter all over it!
Then cut into pieces a bit like a flapjack.
Will stick onto backing I think as a bit flimsy, but I think they look quite nice - the blue ones especially.
Just sharing in case anyone wants to do some x
