As I had a few last minute Christmas cards to make I returned to a technique which is quick and easy and I think effective also perfect for a OLC. Firstly I stamped the background using an acrylic block, I inked the block with Distress Ink tumbled glass and spritzed with water then stamp onto the card, depending how much water you spray depends on the effect you get, also any dye based ink works I've found. My first card is the one I'm entering into the challenge and has been spritzed quite heavily making a very subtle water effect background, the second picture shows different effects with less spritzing.
Snowflakes SU set Snow Burst and SU inks Night of Navy, Pacific Point and Marina Mist were stamped randomly over the area stamping off the block of background, using the stamp-a-ma-jig I over stamped in clear embossing ink onto some of the snowflakes and greeting and added Stampin' Up! sticky stuff - I love this for glitter as the glitter really doesn't seem to shed - then glittered with ......... The sentiment is an old stamp I have had for years and no idea to its origin. Try as I might I could not get the glitter to show as the effect is very subtle but sparkles well in the light.
These cards show the effects with less spritzing
Hope all your Christmas preparations are going well
bye for now
