I also made for a friend of mine who is a homeroom mom. 31 flowers in all :)
There are four types of flowers. For the first flower I used a freebie from SVG Cuts - from 1/21/10. Just weld the rose_bottom.svg to create a card to hold the gift card.
Second Flower is also a freebie from 4/14/10. I welded the center of the tulip and glued the edges. It is a little pocket.
The third & fourth flower uses elements from SVG Cuts 3D Mums & Fall Flowers SVG Kit.
Flowers are about 4" - big enough to fit a gift card. I finished these off with some inking, embossing and Creative Charms Embellishments. So if you are thinking about doing an end of school project for your teacher consider a Gift Card Bouquet!
