I've managed to get hold of some more wooden plagues to play with. I've used a mixture of Adirondack inks and Versafine inks, along with some Tim Holtz black and white enamel for detailing. The flowers have all been dipped into ultra thick embossing powder in the melt pan.
It's quite hard to blend the inks on wood so after the first attempt I decided I'd just stamp directly onto the wood. I'm not particularly keen on the last one but it was worth experimenting.
