This, I'm afraid, will never happen. A) because I almost always have someone or two some ones whose hand I need to hold or whom I need watch like a hawk to make sure no sidewalk licking is taking place, or my hands are just full of two backpacks, tow coats, a discarded scooter and a bag of groceries. But even if that were the case there is B) the fact that I am totally uncoordinated and knitting while walking would just lead to face plants and possibly getting hit by a taxi, because they rely on you watching them, not the other way around.
But just because I can't walk and knit doesn't mean those little project bags wouldn't be handy. Since then I've actually noticed a lot of knitters with them. And it makes perfect sense. Instead of toting a whole separate knitting bag with you, these small, squishy bags can be stuffed into your normal purse and they will keep your yarn and needles from getting tangled with your string cheese and ipod earbuds. They also keep your yarn from rolling all over the place while your are sitting around the living room (park, kitchen, playground, subway) knitting.
I could buy one, yes. They sell them at every knitting shop around, but why, when they are so simple. Plus I had a bunch of ripstop fabric out yesterday while I was working on making a draco lizard costume (Don't' worry, I don't know what a draco lizard is either. My kid, he picks the weirdest things to be for Halloween).
You could make this smaller or bigger, depending on how much storage you want. I'm working on a sweater and have a few more ready to cast on when this is done so I wanted something that could hold a lot of material.
You'll need:
1/2 yard of fabric - lightweight is best, ripstop was perfect
1/2 yard of double fold bias tape
1 yard of cording or ribbon
Along one of the long sides, fold the bias tape over the raw edge and use zigzag (or straight) stitch to attach. I used a contrasting color since the bias tape I had was the same color as the fabric. Needed a little zing. Ya know?

With the channel sides out, fold the bag in half (hamburger style) so that the bias tape ends and the ends of the channel meet.
Sew along the bottom and trim the excess fabric on both bottom and side seam so they are nice and neat.
While the bag is still inside out, run the cording/ribbon through the channel and then tuck the tails through the opening you left at the ends of the channel so that thy will be on the outside on the bag.
