The minute I saw the challange photo, I was drawn to the floral pillow. Although this is such an awesome photo, I've already got two other ideas for future cards!
And here's my card -
A one layer copic card. The details got washed out a little when I edited the lighting, so here's an unedited version.
I embossed the dahlias is white, then coloured in with R00, R02, R20, YG91 and LOTS of blender pen. The sentiment is one of my all times most used - from Giga guidelines.
Supplies; Stamps - Delightful dahlias, Giga guidelines (sentiment), Paper - white, Other - copics, white embossing powder.
