I've had in mind to try out a technique - Double Masking - that I'd seen on Pinterest. I thought it would look good in the challenge colours and it uses circular elements. The instructions were on Sandi MacIver's blog where she makes a fabulous card with the Love and Affection set. In her stunner of a card, she colours the images with Stamp'n'write markers, which would be much easier than actually stamping the big images in terms of getting a good clean edge - but since I didn't have the markers I had to do it the hard way!
I do like the way it looks as though the flowers are floating in bubbles although I think you could use any shaped mask if you wanted to. Anyway, it's a great technique and I'm keen to try it out again. I'm thinking it might work with Seaside Shore - I'll let you know!
