[ I do lots of knitting but hold the right needle between my legs, manuver the yarn in my right hand and hold the project in my left. Looks goofy but works for me.
My grandmother taught me crocheting & knitting by sitting knee to knee. I can crochet easily but I couldn't get the hang of knitting because my right hand just is too clumsy to hold up the knitting needle correctly so I tried the way you do with the needle between my legs. Unfortunately my yard got tighter and tighter until I choked it and it just wouldn't work for me. I gave up and went on to other crafts instead.
