Recently I've bought a few paper punches for scrapbooking. I haven't tried them yet, but my children have :)
They managed to use all of the different shapes: flowers, leaves, hearts, as well as quilling strips and colored papers.
Everybody had their own style and design. Next time we'll make a mosaic from colored punched shapes.
So, dear quillers and scrapbookers, don't throw away pieces of paper left after your work, just give them away to your kids and watch them using this scrap in their projects :)
