I had a stack of old used children’s beads, and now my children are getting older, I wondered what to do with then all. I had a silicone heart shape and put in a layer of beads into the cake shape. I put them in our caravans gas oven on the highest setting for around 20 mins. (I decided to do it outside as the fumes could be dangerous.)
This is really quick and easy and the results are beautiful. We made lots of small ones and gave them out to friends and family at birthday times.
