I buy most of my Hama bead pegboards individually from the craft shop in my village. They have a great selection, and they are reasonably priced. Most of the boards that they sell are also available in the larger Hama bead sets, but I like to buy the boards and large boxes of beads individually, and if I need inspiration there is plenty online.
I bought this Hama bead princess pegboard with the intention of making some pretty princesses for Mia like the ones in this set from Craft Merrily, but with Halloween approaching I thought that instead I'd have a go at using the board to make some witches! I also had to stock up on bags of black Hama beads, these boards do use them up quickly.
