Also acquired in the past few days:
The Opinionated Knitter, by Elizabeth Zimmermann (Zimmermann spent her life turning traditional knitting inside-out and upside-down, popularizing seamless knitting in the round and inventing amazing new garments, like the Baby Surprise Jacket, which is knit in one bizarrely-shaped piece, then origami-folded and ends up only having seams shoulder to wrist along the upper arm ... one of the reasons I wanted this particular book, aside from reading Zimmermann's quirky and funny writing, is that the instructions for the adult version of the Surprise are in it)
Double Knitting, by M'Lou Baber. A technique I want to try sometime ... reversible garments with the pattern in positive/negative on each side (click on the title link to see several examples from the book)
P.S. Yarn Harlot's take on Surprise Jackets is too funny not to share ... even the non-knitters should get most of it. ;p
