It's funny, I had never heard of this product until this week and then I see it mentioned twice! Once in a project in the latest Craft Stamper magazine, and again on the Ready Steady Stamp! challenge blog. Isabelle Norris has used it and has also posted a demo of it on her blog. As usual I can never resist a new craft product so I ordered 4 pots of Paper Soft from L.B. Crafts yesterday afternoon. To my great surprise they arrived this morning - what fantastic service! The new challenge on RSS includes using this product if you have it, and the colours are green and brown. By a strange little bit of serendipity I had actually picked these two colours in my order. So I am planning to try it out over the next few days and also to complete my project for the challenge... so watch this space!
Paper Soft is a water based paint by Viva - specifically developed for papercraft. It comes in a jar with a big sponge on the top, and you can pick up small amounts with cut & dry foam or similar and then blend onto your cardstock.
