Ooops, couldn't resist this vintage box of threads off Ebay!
If it had been full of Sylko reels of thread I would have been happy.
These are even better
Pure silk embroidery thread in a rainbow of colours
I have used this type of thread before, hording a couple of reels of it. It's lovely to sew with, doesn't knot up and glides through the material.
Not sure how old it is, going by the colours 30s or 40s? I Googled Pervale and apparently it was a Mill in Greenford, Middlesex.
I popped in a local charity shop last Friday and bought a tatty looking box which as usual I forgot to take a "before" photo. Painted it with Laura Ashley eggshell and cut out a leaf design from the Laura Ashley paper that I have just used in my bedroom. Also lined the bottom with the paper.
