These cards are the ideal size to frame or mount onto greetings cards, so not only are they a useful practice tool for someone getting to grips with alcohol blending and shading, they're also useful for the crafter or cardmaker too :)
All 4 packs are available for £24.99 from Card Craft-UK, although Out Of Stock at the moment they are getting lots more in soon.
Here are my finished cards from each pack!
