Stained Glass Celtic Knot – a bit of fun using old bike parts, great for those with a passion for bikes! I have used an old clutch plate and inserted a celtic knot using just simple lead and textured clear glass. Made using traditional stained glass techniques. It looks great in the shed along with all the bike paraphernalia and memorabilia, it can also hang in the garden, or in a window. Celtic Knot I love these Celtic symbols with their interlace patterns, complicated in glass to get them even.
