One of the stamp sets I love to play around with is "Clockworks". It's not really my usual style, but I love the collage effects you can produce with it. Here's the birthday card I made for my Dad's birthday this year:
It's all on one layer, which is really handy when postage is an issue, but I think it's SO effective. The colour scheme is straight from our fabulous "Color Coach" (sic - sorry, I'm not good with these American spellings!)
I hope the sun is shining where you are - it is GORGEOUS here - and that you have a really lovely weekend, whatever you're doing. Back soon!
