Here is a textured tree branch piece that I fused w/2 pcs. of COE 96 glass then incorporated into this panel.  The soft amber surrounding the center pc. is Wissmach iridized which I have on the backside.  When you hold it up to the light, soft beautiful greens, pinks, and ambers show thru, which picks up in the skinny green strip, along with the brown in the frame.  Nice………  🙂  🙂  🙂
