Putting a pocket in a shopping bag

The other day, I needed to run to the store to get something, and, as usual, I didn't have any pockets (why don't they put more pockets in women's clothes?). If it was winter, I would've put on my coat and used its pockets but now that it's nice and warm (finally :D), I wasn't going to do that. So, rather than bring my shoulder bag (along with all the random stuff that's always in there), just to hold my wallet and keys, I decided to throw them into the shopping bag.  It just made me think, this thing really needs a pocket.

Well, yesterday, I was going through the stash of scraps that Aysha gave me last year, and guess what I found? A pocket! She had unpicked it off a shirt. If I'm not mistaken, it was this shirt.

So, I turned my shopping bag inside out, pinned the pocket on, ...

...stitched it and I was good to go!
