I didn't end up taking very good pictures, so if you need help, feel free to ask for it via PM or IM (AOL IM- caroleeeeeeeena), and I'll do my best to answer your questions.
Heeeeere we go!
Step 1: Draw and cut out your pattern.
There are three pieces to this pattern: the outside, the lining, and the strap.
There are dimensions on the pattern pieces there, but they don't really matter- just get the general shapes down and you should be fine.
Step Two! Cut out your pieces.
You'll need about 20 inches of fabric for the outside, and a little less than half a yard for the lining, using my dimensions. Again, it's going to vary. Cut 2 of the lining, two of the outside, and one of the strap, cutting the strap on the fold.
Step Three! Make the tucks.
If you see there on my outside pattern piece, I've got little triangles drawn in the bottom corners. What you're going to do is make little marks on the fabric at the outside edges of those triangles, and one up the middle. What I did here was made little cuts to mark those spots.
It'll look something like this:
Next, pinch together the fabric at the middle of the triangle, so the two outside marks meet.
Fold this little flap of fabric over, toward the outside edge of the bag, and pin it in place.
Do this for all four tucks, on both pieces of the outside fabric.
Step Four! Pin everything together.
Pin the two outside pieces together, right sides together.
Pin the two lining pieces together, right sides together.
Pin the right sides of the strap together.
Step Five: Sew!
Sew, turn, and topstitch the strap.
Sew around the outside of both the lining and outside fabric pieces, leaving the top open. Turn them right-side out, and marvel at your bag starting to take shape. If you want to add a closure (like a magnetic snap or vel-cro) to your bag, sew it to the lining at this point.
Step Six! Pin the top edges together.
This part is kind of funky, and also where my pictures started turning out bad. You turn the outside fabric inside-out, and lay the strap down inside of it, pinning it where you want it to go. Turn the lining fabric inside-out also, and pin it along the top edge. What you should have is a little "purse sandwich" with the right sides of your lining and outer fabric together, with the strap sandwiched between them. The Jordy tutorial explains this better than I do, with better pictures, so you can check that out if you need help.
Pinning on the strap:
Step Seven! Sewing Machine Jam. (Skip this step for best results.)
Step Eight! Sew the top edges together
Sew around the top edges, where you have pinned. Leave about 3" unsewed, so you can turn it right-side out.
Step Nine! Turn it right-side out and topstitch.
Pull everything through the hole you left in the top edge stitching.
Get it all situated right-side out.
Topstitch the top edge!
Aaaaand you're finished!!
Post pictures here if you make one, I'd simply love to see them!
