Wool fabric. This is the real stuff, it came from a clearance of 100% wools from an old tailors shop and occasionally we get a whiff of mothballs. All 100% wool. It is split width, so the actual width of the fabric is around 27/ 30 inches . Very low prices!! We have thousands of metres but it is not repeatable. We have not washed or tested the fabric. Most have woven selvedge.
