I'm sure people do this already, but i thought i'd share.
As it's the season for eating bucket loads of Roses and Quality Streets (or is that just me ), you can save the coloured squares that some are wrapped in (not the foil) and add them to your art/craft box.
Current favourites for DS is to make stained glass window pictures to hang by a window and cardboard glasses with a different colour wrapper for each lens; makes the world look fantastic!
