I viewed the video only to discover that I have made the same bag a couple of years ago. The pattern was from another online quilter and one her site. The directions in this tutorial are clear and accurate. Just to add a tiny touch of bling, I dug into my jar of old buttons and stitched one on the flaps to keep it in place to personalize it just a bit.
I highly recommend this little bag as a clever simple reusable gift bag or craft table sale item. I made most of mine with Christmas fabric that needed to be put to use, so it turned into a good stash buster too!
