The "vase" is a Crystal Light container covered with pink felt. The heart is painted with Martha Stewart Glitter paint. You can find patterns for crocheted hearts all over the 'net.' I also cut some hearts from felt painted with glitter paint. The stems are stuck into a piece of Styrofoam.
This is on top of a hutch now, but if I were to put it someplace where you could see both the front and the back, I'd make doubles of the crocheted hearts and sandwich the stems between them. These are just 'sewn' in place.
