The felt is first sealed with fusible webbing. The webbing happens to have a very slight irregularity in thickness. When a mix of PVA (white glue) and metal powder pigments is lightly brushed over this webbing some of it soaks into the felt and the rest beads up on the surface. This gave me the stippled, hammered-metal look with hardly any effort at all. The feathers can then be glued on and silvered with acrylic gloss medium and metal pigment. The acrylic medium is not as heavy bodied as the glue so that the fine detail of the feathers is not lost. Figuring out the materials for the knot pattern is still a work in progress.
