I saw in Recent Activity that you were querying the number of stitches needed for a rib pattern from the Pattern Book. I don't know if you are referring to the 6 stitch one or the 2 stitch but yes, all rib patterns are very stretchy. I made a few of the 6 stitch for this theme recently and thinking like you I decided to use 33 stitches, forgetting that I would then need to slightly modify the pattern on the 'wrong' side. I ended up with a perfectly acceptable square but not the one illustrated. In the photo below the one on the left has 33 stitches and the rest 30. You do need to measure the length of the square whilst still on the needle as when you pull it out to 8" you find it's not as long as you thought. It is does actually work up very fast and is great for using up scraps as colour changes become a part of the pattern. Sorry to butt in but I hope this helps.
