No. Never tried it. I'm not the creative, crafty type. I did knit a jumper for my newborn son once, but it really wasn't for me. My dose of creativity is aimed at photography, cooking and writing. Otherwise the crafty gene skipped a generation. My Mum seems to like to knit. She has made almost a whole clothing store for my new grandson !!
I have heard of it but not tried it.
Like Rice , my concern was for frequent calls of nature. There is probably a technique for holding stitches on something other than the arms for breaks.
I don't know what I would want to knit with such a loose weave lthough I think it looks terrific.
I've never heard of it. It looks fun, but I imagine that you would need to sit for quite a while - it doesn't look achievable with 3 kids constantly at me...but as a project to do if I had a spare couple of hours I think it would be fun!
