Check out this fantastic tutorial using colourwash sprays to create a great 2 tone background using rubber stamps! I love the whole grungyness of it, check it out:
Also check out The Last Door Down The Hall blog for some gorgeous vintage collage wheel freebies, I just love the softness of these colourwheels and the way all the colours blend in together to seemlessly. Admittedly Ive never used one as I trust my own colour muse but they are handy to use if your colour challenged. While your there check out the other eye candy too as theres some gorgeous artwork - though I must admit Elizabeth must be on the crazy side for creating 120 Bandana technique pages for a swap!!!!!!
