It's a Potter Craft book from Random House and the correct title is 400 Knitting Stitches, a Complete Dictionary of Essential Stitch Patterns.
I don't know if Potter Craft is a series of crafting books by this publisher. I don't recall seeing others with this name. What caught my eye was the cover photo. It was of two stacks of dish/wash cloths, each in a different stitch. I love making these! Quick and Easy, almost instant gratification, and a great way for me to learn new stitches.
It's a softcover and under $20, so I might just treat myself to an early Mother's Day present.
