Large paper or multiple pieces taped together
1 yard heavy-weight fabric for the exterior
12" of accent fabric for the front (I used a cotton, but a heavy-weight would work too)
1 yard cotton fabric for the lining
2 1/2 to 3 yards 5/8" wide grosgrain ribbon
Padding for the shoulder strap (I used a felted sweater)
1. Begin by creating your pattern. Download the Pattern Guide. Things are going to get a bit technical, so if you have questions, don't be shy, please email me at firstname.lastname@example.org and I will try to get back to you within a day or two. Draw one of the red boxes on your large paper, then use the guides/measurements to create the angles. The accent panel and pockets are the purple lines on the the piece labeled "Front Angled Pieces". Replicate the Front Angled Pieces, add the seam allowances, then trace each accent piece onto another sheet of paper. THE SEAM ALLOWANCES ARE NOT INCLUDED IN MY MEASUREMENTS, YOU WILL NEED TO ADD THAT BEFORE CUTTING. I did my seam allowances at 3/8".
2. Now cut your fabric. The picture below shows what to cut from each fabric. I cut the strap later, so you will also need a rectangle of both the lining and exterior fabric measuring about 4" x 35". you will also need a couple of rectangles from the exterior fabric to go inside the pockets. Don't worry, though, you should be able to get this from your left over fabric. (By the way, those pictures were all taken in the same light on the same carpet. Its amazing how different colors on the same background change the color of the background...)
5. Cut a rectangle of your exterior fabric to go inside the pockets. (I forgot to include this in my pattern guides and I don't have exact measurements, mostly because I just winged it. I used a crochet hook to see how wide/long I would want it then cut away). Create a rolled hem along the top edge, then baste around the remaining sides about 3/8" from the edge and clip the corners. Fold along the basted stitch and iron. Place on one of the side panels being careful to make sure it doesn't poke above the pocket. sew in place. Sew down the center of the little pocket. Place the larger pocket on top of the front side panel and baste around the edges. Sew a length of ribbon along the long edge of the front side panel. Repeat this step for the other front side panel.
6. Line up the center front panel of the accent fabric with one of the front side panels and sew. Repeat for the remaining front side panel.
8. Now to the strap. The "stuffing" piece is totally optional, but I like the structure it gives. I used an old wool sweater I found at a thrift store that I had felted for some stockings last Christmas. You will cut this to a 3" x 35" rectangle.
9. Pin right sides together of the exterior and lining strap pieces and sew the sides. Turn right side out and iron along the seams. Attach a safety pin to the end of some ribbon, then thread the ribbon through the strap pieces. Attach the ribbon to the stuffing piece and gently pull through the strap pieces, taking care not to twist the stuffing. Top stitch along the sides to hold the stuffing piece in place.
10. Match up one end of the strap with the top edge of one of the exterior side panels with exterior sides together and the strap falling toward the bag, then sew along the top with a zig-zag stitch. Repeat for the other side of the strap/side panel.
