I am doing a practical archiology project with the U3A (University of the 3rd Age) together with the University College of London to reproduce a copy of a 1500 year old Coptic Sock which is in the Petrie Museum at LUC. You can see the sock at this address:- http://www.petrie.ucl.ac.uk/detail/details/index_no_login.php?objectid=UC16766&accesscheck=%2Fdetail%2Fdetails%2Findex.php
While we think it was worked in one needle knitting it might have been done on a knitting loom. My questions are "Do you know any history of the knitting loom?" "Are there any reliable references to where I can find our when knitting frames were first used?"
