It took less than half an hour, and look at all the stuff it holds!
Truthfully, I saw a really cool pattern in an Amy Butler book and that's what I started out to make. But I couldn't figure out what was going on so I .... improvised.
Ok so you take a rectangle of fabric (I just chopped off a section of half-yard) and fold it in half with right sides together. Stitch each long side. Keeping it inside out, make a gusset on the bottom. (If you don't know what I'm talking about, google it. Cuz I'm not a very good 'splainer.) Or if you're even lazier than me (not judging!) skip that part. It just won't be as full-looking on the bottom.
Anyway, do the exact same thing for your lining. Now turn the printed piece right side out and leave the lining inside out. Fit the lining down inside the bag, doing your best to match up the gussets and the top edge.
To make the tube around the top for the leather handle, you'll basically make a big ol' hem on each side, without closing them at the seams. You're probably supposed to iron down a quarter inch and fold over again and then stitch, but I'm lazy and I hate ironing. So I folded the edge down a tad and stitched, then folded it over again and stitched, making it big enough to fit a safety pin through.
The hardest part is actually getting the leather in there. (BTW, you can get leather lace in all kindsa cool colors at the craft store in the hippie aisle... more about that later.) I don't have any special leather stitching or whatever tools, so I took a nail and hammered it down into the darn thing to make a hole for the safety pin. After threading it through the big ol' hem, Amy Butler says to stitch it together. Bwahaha. I just tied it in a knot. Meh.
What I love about this bag is (gasp!) the simplicity. As long as you're not too impatient to pre-shrink the fabric before you start stitchin', you can drag it around and toss it in the wash without worry. If you make the straps just the right length, you can wear it on your shoulder and fish stuff out with one hand pretty easily. Plus, even for the snazzy stuff, it's not more than $5 for a half yard. So it's cheap enough to make one in all your favorite prints and not worry about what happens to it during your busy day!
