A while ago I managed to pick up some old Pearsall's silks from a friend, who in turn got them at an auction of bankrupt fishing shop stock, I think it was. The silk is on wooden bobbins, and just out of interest, I am trying to put some kind of date to them.

Anyone any idea when Pearsall's changed from wood to plastic bobbins? Just approximately even?
The colours are lovely btw - more muted. Whether this is due to age or changes in the dying process I don't know.
