I bought this fun ergonomic interchangeable hook set! It comes with four hook "heads", but none of them were my favorite size, so I had to buy the "extra set". This set is sold at www.Motionmagique.com I really like it, though I admit, I'm having a little trouble getting used to it. Apparently, as I make my stitches, the yarn comes further down on the shaft than I realized, so occasionally, my yarn "sticks" on the little black rubber "O" rings. It feels good in my hand though, so I will keep trying.
