One of my latest toys is the Addi Express. I read some reviews and looked at the product and decided I had to have one. It knits tubes using ww yarn. Mine was purchased at Paradise Fibers because they had the best price. It's very easy to operate as long as appropriate yarn is used. I've tried JoAnn Sensations and leftover bits of different kinds.
I had no interest in making scarves but came up with a way to make fingerless gloves. I knit the tube with scrap yarn at both ends. Then I put each end on needles and did some ribbing. After that I cut 4 stitches where I wanted the thumb, did a row of single crochet which was put on needles, and did 4-5 rows of ribbing.
What I really wanted to make was socks. Then I learned Cat Bordhi had written a book of patterns just for the Addi Express. Paradise Fibers carries Quick Knits for the Addi Express and it includes patterns for socks, a purse, a scarf, and earwarmers. The directions are very clear and I've made quite a few socks. The only thing is that lightweight yarn doesn't work. Since my stash included lots and lots of JoAnn Sensations, that's what I've been using. The socks are very soft and stretchy but are more like house socks than for wearing with shoes. Just like with the fingerless gloves, the Addi Express makes the tubes and rest of the sock is handwork. But I find it much faster than doing the whole sock by hand and it's a nice change.
