Step 1: Stuff You'll Need
- Thread appropriate for your fabric, I used a #80 polyester.
- Industrial Sewing Machine
- *Scrap of leather
- *Laser Cutter
* If you want a name patch.
Step 2: Cutting Your Pattern
Cut another piece 36" x 12", this will be the main compartment of you bag, I chose to use a different color of fabric, but it's obviously up to you. You can use one of your discs to trace an appropriate french curve at one of the 12" side's corners for the bag's closing flap. Cutting all of this to these dimensions gives you a fair amount of wiggle room as far a seam allowance, I tried to keep mine at a 1/4".
Cut one more piece 9" x 6", this is your H2O / PBR holster.
Step 3: Making Your Shoulder Strap
Turn right-side out. Warning, this may take some time and cause mild arthritis, be patient.
Iron flat with seam centered.
Sew each length with 1/4" from edge.
Fold ends over and iron flat, then sew 'em.
Step 4: Prepping the Bottle Holder and Bag Farbric
Fold in half, good side in, with 9" edges touching. Sew bottom of bottle holder closed with a 1/4" seam allowance. Then turn right-side out.
Iron and Sew the 12" edge (without the curve) of your 12" x 36" fabric.
Step 5: Assembling and Attaching
Sew these pieces together down the strap, continue by sewing 2" of your bag fabric (perpendicularly to the edge you just sewed) along the width of the strap. This will create the bottom of your disc carrying pocket or main compartment. Then pin and sew the fabric up the strap, stop when parallel with the front panel you already sewed it.
Run the strap along the bottom of the bag and pin up the opposite side. I left the bottom loose to hang a jacket or sweatshirt off of.
If you have excess strap material you can fold and sew it on to itself to create another loop to hang something else from.
Repeat sewing sides to strap, be careful to avoid the excess "strap loop" if it applies.
Turn bag right side out.
Prepare the same way you did the shoulder strap. Pin and sew to the inside of flap first. Then fold to outside, iron, and sew.
Your bag is almost complete!
Step 7: Adding Patch
Place leather in laser cutter and etch your design, logo, or name.
Position on bag and attach.
