Weavers Knots

I came across this nice new blog, quite by chance while looking up Universal Tie-up!  How Google thought it was relavant, I don't know, but never the less it's a really useful, but different way to tie a weavers knot!  While you're there take a look at some of Jenny's other posts, too!

The Textile Blog

This is another really useful blog, full of wonderful history, inspiration and detail:

It's a really huge resource and again well worth a scroll down to older posts.  The Islamic section has some wonderful patterns.
