I've recently finished two very different books:

The first is "Make your own dress patterns" by Adele Margolis. I thought is would be all about dresses, but she went through how to contruct patterns for all kinds of clothing. It's not "fun" reading but very helpful reading. The new knowledge it gave me will be of good help when I make the lace "cover" for my wedding dress!

The other book is "Opening Skinner's Box" by Lauren Slater which is an absolute amazing reading for everybody about big psychological experiments of the 20th century.
