I played with a couple of smaller floral stamps recently to make some clean and simple cards. I guess they could have been even simpler by stamping the flowers once but I still managed to keep plenty of white space. To create both cards I inked the stamps with memento markers, spritzed the stamp with water then stamped on watercolour paper. I did some extra blending on the poppies with a paintbrush and stamped repeat prints without re-inking, which explains the difference in colour intensity.
To stamp a group of three sunflowers I inked only part of the stamp each time so the flowers could nestle into each other without the leaves and stems getting in the way. The layouts are the classic black mat+black sentiment deal.
