In my blog hopping this morning, at Needle 'N Thread I came upon a link to the online Project Guttenburg, which includes an Encyclopedia of Needlework by THÉRÈSE DE DILLMONT. I believe I have heard her name from the experienced tatters at the Palmetto Tatters' Guild.
Here is one portion related to tatting. It is awesome with delicate and beautiful work that I have not seen before. There are instructions for many of the patterns, and perhaps one day I will be able to decipher them into something I could work with.
