This store doesn't even look like it's open half the time, poor window display and very limited stock, BUT that said, it is worth checking out for wool and general supplies - I bought some fusible interfacing at £1.40 per meter which is a good price and meant I didn't have to trek to town on a Sunday.
Fabrics are very limited but you will find cheap canvas, burlap and wadding here.
Jeanette Fashions specialise in a range of materials and fabrics including fur.
