I love mini Hama beads and I think they make perfect embellishments for simple Christmas cards. Here's my version of a mini Hama bead Christmas pudding.
Once all your beads are in place you place your ironing paper carefully over your beads and iron carefully until the beads start to show through the paper.
Leave to cool and the stick to your card blank. I simply printed "Happy Christmas onto my 10cm x 10cm cards fronts and stuck the puddings on with Diamond Glaze.
