You can buy felt at Wal-Mart that are adhesive backed (awesome!) plus I recently bought a cuttlebug and some some flower dies and the two combined make for some awesome flower embellies. For those that don't have a die cutting machine, you can buy the adhesive-backed felt and trace a pattern on the back and cut it with some fine-tipped scissors. The regular felt is harder to cut.
The adhesive-backed felt is stiffer, and easier to cut and shape. I also tried the regular felt and the cuttlebug flower die cut through perfectly, you just have to figure out how to adhere it properly.
I also cut the adhesive-backed felt with my MM trimmer and made a ribbon-like border. I also used my fiskars tool (like an exacto) and cut a wave pattern fopr use on the notecard.
Anyhow, here are some samples of what you can do with a piece of $1.50 felt from WM and a die cutting machine. I only tried the Cuttlebug and one Sizzix die (the Cuttlebug worked better) but I would imagine it would work for different types of machines.
