The Shetland Museum and Archives has textile photo archive available. I think this particular photo is interesting because it shows sweaters (jumpers!) being blocked (dressed!) on wooden forms and I kind of wish I had a few. I wonder when these fell out of use (or have they?) and whether or not making modern versions would be a good business idea – surely someone has already considered it. Also, the shawl being blocked is pretty incredible, so fine that you can see the woman standing behind it.
