1) "Pulled Thread Embroidery" by Moyra McNeill originally published in 1971. This is the Dover edition reprinted in 1993. For it's time this book has lots of great photos - all black and white. Stitch diagrams are drawn. Has some funky, artsy stuff. I'm saving this one for that later encounter I will have with pulled and drawn thread.
2) "Bargello Plus" by Mira Silverstein published in 1973. This book has both black and white and color photos and a beautiful peacock on the cover. Has a section on figuring out borders and miters for bargello work. I think this book may be very helpful in my near future.
3) "Four Way Bargello" by Dorothy Kaestner published in 1974. Has both color and black and white photos. I think the color ones are necessary for understanding the dimensional, kalidoscope effects of this technique. I was hoping that maybe there would be a bit about eight way, but no. This book is about to become my other new best friend.
I can see that I need to start cataloguing my books. Another project!
