I bought a set of the round Knifty Knitters last week, using the 40% off coupon at Michael's, but I have yet to try it. I also bought a long wooden knitting board a couple of years ago but haven't yet tried it.
And I just found some more neat sites, which you can do a search for. Because of a Lion brand post on FaceBook, I found the Loom Dude who uses knitting looms; and because of an article and pattern in a crochet magazine, I found Crochet Dad who uses finer yarn. Another is the site for Drew Emborsky, known as the Crochet Dude, who has been crocheting since he was little - said his dad used to crochet rugs for their house. Drew designs things for everything and everybody, and uses a lot of post stitches.
