Here is a card I made for the April challenge at Stamp School (http://www.stampschool.com/). The challenge was a photo inspiration with the following colours: pink, green and white. I added black because I think it made the card stand out more.
By the way, Stamp School is looking for people to enter their challenges, so go check it out!
I created the checkered background by weaving quilling paper. I cut out a heart shape opening on a square of card stock and layered the woven paper behind the opening. Then I made the spiral roses and cut the leaves by hand. For the stems I used think floral wire that is covered with green tape.
