Today's sewing project is a small lined pouch, suitable for putting a set of keys and a pocket knife in, so as to protect the trouser pockets of the owner. This is our preferred solution, rather than having to reinforce multiple pockets (argh) or a drawstring bag (risk of the string tangling in the pockets).

I have a pouch that's perfect, but it is used as as sewing kit, and I don't wish to give it up. Instead, I went hunting patterns. I haven't found quite what I'm after, but the two links I like (one text, one video) are

text (with some pics): Damjana Jakos at Apple Green Cottage has a small pouch sewing pattern - with linked paper pattern if you wish. This wasn't quite what I wanted, because some of the lining is done with the outer fabric, and I'm planning on using a heavier lining for functionality and a lighter cover for aesthetics. Also because turning two heavy fabrics at that size will be horrid (the heavy fabric is likely to be an upholstery weight cotton, because that is what I can think of that I have). I also wasn't enthused about the janky sewing on the inside.

video: Connie Brad at The Craft Channel Easy Lined Pouch - First Sewing Project. Stylistically, this is much more what I'm after, but much larger. However, it helps to watch the larger one being made. If this one interests you, it is worth watching the whole thing first, because at least once there is a 'oops, should have ...'. Mind you the one I noticed was 'should have used more pins', which yes, a beginner would certainly need more pins than that! While usually I hate video tutorials, this one is 10 minutes, shows me what I need, and I can work out how to convert to what I'm after.

So, the differences: I'm looking to make something roughly 5cm square, and the front closure will actually be a ribbon (or possibly a thin fabric band) sewn into the side seams that the front flap slots under.
