No, it didn't take long. Duration was 11 days but I didn't knit every day. Only when I had time between work and school. The pattern is easy to memorize, and it's even better to keep track of if you use markers between every 8 stitches, where it changes. If I didn't, I would've got lost because I tend to watch TV, and I'm not THAT good of a knitter yet.
Also, my version is only 21.5 x 25.5 inches. So it's not very big, but I think it's a great size for newborn/infant.
