If you are wondering what Opus Anglicanum (which translates to "English Embroidery") is, there's a nice but brief introduction at http://www.bellaonline.com/articles/art68868.asp\
Tanya specialises in the technique and her blog makes very interesting reading as well.
This technique was the mother of Or Nue and the tutorial is relevant to those interested in that technique as well.
Now, who was it that was talking to me about the needlepainting book "Embroidery from English Gardens"? I've finally received a copy from the library, and I'm ready to talk about it..... :-)
