I use tissue paper squished into a ball with damp fingers. This forms your base on which you then create your design with the polyclay, right over the tissue. Bake as usual and when cool, place the bead in a cup of water for a few seconds to soften the tissue, then remove it with tweezers. It will shred and pull out in small pieces. Two Hints: 1) Don't underbake or the filagree will be too fragile and 2) make sure the two "hole" areas of the bead through which the cord will pass are in an area where there is a fair bit of clay supporting the holes, or reinforce the area with a small clay ring prior to baking. You can also use small jump rings, attached with super-glue after baking. It is so maddening to have something you have slaved over for hours crack or fall apart. Have fun claying!
