This participant sent in pictures of a tree skirt.
She writes: "This is a 75 Christmas Tree Skirt I did for a charity auction. I used red velvet with embroiderd Cardinals (approx. 5x6 large hoop) on tafetta panels (your suggestion on using felt as a stabilizer worked!). To add a little sparkle and fill space around the Cardinals, I used glass beads in two different sizes to imitate scattered red berries. The whole skirt is padded. For the sewing and embroidery I use Pfaff Creative 2170."
