I treated myself to a couple of pots of Wendy Vecchi's Embossing paste the other day. It was good fun to play around with and I lost all sense of time. However, as lovely as the results are, it took a few trials and several errors before I began to have success. The white paste was pretty easy to master. The translucent one took a bit longer. There's a fine line between spreading on a layer which is too thick or too thin.
And given that there's a fairly long drying time, I didn't know if my technique had improved until several hours later. However, I stuck with it and came away with a couple of samples which I used in making cards.
Not easy to photograph either as the light here was quite dull but I think you can see the gist of the effect you have.
I shall continue to play with the pastes and dig out some more stencils. I'm determined to master it. If only it wasn't so darned messy.
