Update on the linen/viscose from Pound Fabrics: it's been washed & pressed, it's lost a bit of stiffness but will be good for a dress or top. Drapes even better than when it arrived. The muslin - 4m of it - has 2 flaws each running across the width. I'll have to cut round them. It was only £2/m though. After washing it's crinkled up like 1960s cheesecloth, perfect for DH's summer shirts & it won't be ironed.
