Two individual celtic knot stained glass patterns, each a different colour, weave together to create this panel. I tried to match glass in the dark knot so the colour would appear to flow throughout. This is a fairly large window and needs a sturdy frame. Pattern is suitable for copper foil only. â�¢ 24" X 24" â�¢ 209 pieces â�¢ level of difficulty advanced â�¢ materials list and colour photo included Download the pattern PDF after purchase!
