Whereabouts in Ireland will you be? Last time I was in NI I went to Armagh and there were about 3 quilt shops in the area. I was with a local who was able to take me, they were quite tucked away. If you google you should find some. Fabric is expensive. Enjoy your visit Ireland is a beautiful place. If you're in Dublin take the time to tour Trinity University and the Book of Kells exhibition.
