insanenewknitter, thanks for looking and for your kind praise. Are they very difficult? I found them pretty hard, and here are my comments on that. Every kind of knitting has it's challenges and this complex twisted knitting pattern was new to me. This kind of stuff is done in the round and has a background of reverse St st which I find hard to keep looking really good especially at needle changes, but with practice it is certainly doable. The tiny stitches are a bit harder to fix when you mess up, which I did quite a bit.
It is a well written pattern and fun to do but it takes some concentration and attention to detail. It is probably better to learn this type of knitting when you are young and your mind is alert, so go for it.
