This is one method I use to make quick blue backgrounds. Fill a mister with water. Add a few drops of blue distress reinker (Stormy Sky works well) and a small spatula of silver Perfect Pearls. Put the top on and mix, then spray over white card. When it runs out, repeat using a different blue reinker to add some depth. White patches of card are OK, it just looks like a snow-laden sky! Just leave the card to dry, cut to size, and sponge the edge with some matching distress ink if required.
The blue background on this card is actually packaging recycled from a Marks and Spencer cake box. Well, I had to buy it, it was the perfect blue for my project... and then I had to eat the cakes :-)
