I love texture paste! If you use it through a stencil you can get all kinds of effects. If you layer it onto a painted surface it will pick up those colours. If you use it straight onto a piece of dark card it will keep it's white colour. Once dry, you can paint or ink it and emboss it. But you do need to clean your stencil and tools immediately after use as it hardens quickly.
Here's a tag I made using some quirky characters I've been developing and a texture paste topping. There are several pastes from art shops but I like the Tim Holtz version which I generally buy from Craft Obsessions.
To see how I made it, here's a video and I hope you enjoy it.
