I have the instructions and music for the Hebridean Weaving Lilt.
It is in a book of four set dances, published by RSCDS - Paterson's Publications. (copyright 1948!) The instructions are VERY long, complete with five
rather complicated drawings. I could send you a copy by snail mail, if you
like. Otherwise, if you know anyone who is going to TAC, I'll bet TACBOOKS
might just have it!
If you want me to mail a photocopy, please let me know your address.
