Hi. What's a Knifty Knitter?
I can tell you that if I make a long scarf, I would usually make it about as long as the person it is for is tall, unless I run out of yarn or have just a little left and go ahead and use it up. Patterns should give measurements and how much yarn to purchase. I think knitting is fun. Seeing those stitches on the needle, watching the ball of yarn turn into something I've made still amazes me.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
