I bought the laser printer decals on Ebay from a very helpful Chinese saleswoman called Carmen. I'll put you in contact with her if you're interested. They work out to be just over $1.00 an A4 sheet - much cheaper than any Australian decal seller.
This is the first decal I've made with my laser printer. The bigger clowns are for plates, and the small ones for brooches, maybe cups. I hope there is enough depth of colour for the detail to show once they are fired, as they are a bit light in places. All experimental at this stage.
