Super Shrink Sheets (Pack of 10) Shrinks 7x Smaller, Sheet Size Approx. 15cm x 10cm, Design Your Own

What you're getting

You get ten sheets here, each about 15cm by 10cm, that shrink down to roughly a seventh of their size when you pop them in the oven. Grab some Deco pens (you'll need to source those separately) and let your kids design whatever they fancy on the sheets.

When you're ready, heat them up in an electric oven and watch the whole thing shrivel into a tiny finished piece. You'll need to supervise that bit, obviously—it's an oven we're talking about. It's a decent bit of hands-on fun if your children enjoy making things and don't mind a bit of waiting around to see the results.
