I just successfully taught my little brother to knit. It took him about ten minutes to grasp the concept and twenty or thirty to actually be able to do it himself. He'll be five in March, so we're doing something very simple. He's knitting a pink garter stitch ("gawtow titch") scarf. He wants to give it to our little sister when he's done. He said, "I am vewy into knitting. I am knitting gawtow titch, and I can do it powfectly." Just thought I'd share.
--------------------------- Others have excuses, I have my reasons why...
I taught my sons to knit about 4 years ago (they were 11 and 7), when we were all housebound with the flu for a week. The younger one (now almost 12) has continued to knit. He is working on a basketweave scarf right now. He also asked me to teach him to crochet (I have only been crocheting for 3 months), and he made himself a beanie in one afternoon.
Rena - just let him see how you hold the needles. Alex has modified what I do so that it is more comfortable for him. Some people might be horrified at how he holds them, but it works for him.
