This is another card I made for Stamptivity ...
Stamptivity Gemstone Stamp; Shrink Plastic; Queen & Co Felt Ribbon & Pearls.
For the embellishments... I stamped the Gemstone stamp onto clear shrink plastic with white StazOn ink, then cut closely around the shape, before heating & shrinking (following manufacturer's instructions) & attaching the finished pieces to the card with glue dots.
There's a bit of a knack to getting this right as the stamp tends to slip on the plastic...several of my first attempts went in the bin! I recommend sanding the plastic & don't worry too much as any inperfections are less obvious when shrunk!
