I have a bead mould which is 9mm but it doesn't create the look I want as the beads are too big and you can see the joint on where the bead maker was pressed. Attached is a picture with the beads I would like to make. Can anyone tell me exactly which bead maker to buy and which size? They sell so many sizes that its confusing what to buy.
