I've always enjoyed doing crafty stuff with DS, but mostly have bought things in the past for a specific purpose e.g. cards and foam stickers etc to make Christmas cards.
He's recently become obsessed by Art Attack and has a long list of things that he wants to make. I thought I'd treat him with a craft box full of things so that we have the stuff to make some of these creations, so any suggestions of what is essentials are beyond paper and paint? We've got some toddler bits and pieces like finger paints and hundreds of Christmas stickers but that's about it.
Something he wants to make needs tracing paper (so that's on the list) and clear but coloured plastic sheets (but I couldn't find these on Yellow Moon - not sure if they are called something specific).
