This is one of my favourite and most popular additions to art supplies! Cardboard! Cardboard boxes, cardboard rolls etc etc. Add in some washi tape and you will have given someone hours of fun and creativity. It sounds so simple but that’s the thing about creative gifts, the more simple they are the more open-ended the possibilities are and the more room there is for creativity. Here is a marble run we created from cardboard rolls and washi tape but cardboard also lends itself beautifully to any kind of sculpture or 3D creations.
