Wow! Excellent book.
I preordered Knitted Lace of Estonia from Amazon a while back and it just arrived. I have browsed through this a couple of times and it has everything I look for in a knitting book: history, construction techniques, plenty of lovely patterns, and a stitch dictionary. I look forward to reading it cover to cover. It is written by Nancy Bush and edited by Ann Budd, so it is no surprise to find it exceptional.
