Celtic symbols feature a lot in my jewellery designs. It's not just because I'm Irish and proud of my heritage. I reckon that these Celtic motifs embedded on a public street wall not far from my home have silently crept into my subconscious and out through my work. After all, artists are much inspired by what they see as well as what they feel. I have walked past this artwork at least a thousand times over. How could they not have influence my designs?
