Remnant Basket, Chapel Street, Dundalk is good for both Dressmaking and Curtain Fabric.
The one up beside Joe Duffy’s is Zhivago’s, they used to be on Capel Street in Dublin. They do Upolstery Fabrics, my neighbour was an Upolsterer and I used to have to collect supplies for him whenever I was up in Dublin.
Craft Fabrics for Patchwork etc, there is a craft shop in Blanchardstown out beside Mama’s and Papa’s and they have a lovely selection of small print cotton’s.
