To make it you will need 1 1/2 yards of two fabrics. I like to use broadcloth. You can really get alot of great designs in the fabric. You will need to cut the fabric as such:
Straps: 39″ x 4 1/2″, cut two of each fabric
Side: 23 1/2″ x 4 1/2″ cut one of each fabric
Front/ back: 13 1/2″ x 11 1/2″ cut 2 of each fabric
Front pocket: 11 1/2″ x 11 1/2″, cut one of your outside fabric.
Begin to sew. Sew outside fabric to inside fabric of strapes. Inside out. Then trim edges and turn right side out. Fold over one end about 1/2″ and sew.
Then take front pocket and hem one edge.
Then sew together your side fabric by pinning it to the back. It will make a square. Sew together. You have to do some magic around the corners but it will work. Then pin your front pocket to the front of the bag. Then you will need to pin the side to the front. Again magic around the corners. Sew together.
Repeat the above steps for the inside minus the front pocket. You can add pockets to the inside of you would like. I chose not to. If you do sew them on before you sew together the side.
To combine the inside and the outside: pin strapes the outside side of bag. Make sure they go down, you don’t want to sew them up. Then turn inside out. Pin it around edge of outside. Make sure seams match. Sew together leaving a 2″ gap to flip right side out. Pull outside of bag thur gap. Press edges, the sew about 4/8″ for edge all around top. I like to do a zigzag stitch. But you can do whatever suits you.
Tie straps together at the length you want the bag to be.
You can really custom the bag to be whatever you want it to be. So have fun with it.
