Recently as I was preparing for a big race, I realized I didn't have a race bag to leave at the bag drop that met the following requirements: 1. Waterproof 2. Unique and easily identifiable and 3: Fit all of my stuff and 4. I wouldn't be horribly upset if it dissapeared. So, I decided to make one for myself that met all of my needs. I thought you might enjoy learning how to make your own race day backpack, so I've composed a tutorial for you. Please let me know if you have any questions. I am happy to help! I would also love to see your finished products, so feel free to post comments and photos below!
What you need:
40 inches x 16 inches waterproof outer fabric (you can also use regular fabric)
40 inches x 16 inches inner lining fabric
4 yards of rope cut into two 2 yard segments (I ordered paracord online).
2. 5/8 of the way in from the side mark 1 in down and 2 in down from the top. Also mark 1 in up from the bottom. Do this for both sides. Pin.
4. Take your 40x15 inner lining fabric and fold it so right sides are together. Mark 4 inches on one side. Pin to keep from moving.
5. Iron seams open on your inner fabric, and outer fabric
6. Turn outer fabric so the right side is facing out. Put it into the inner fabric (which is still wrong side facing out)
7. Line up and pin seams.
8. Sew all of the way around the top edge using a 5/8 seam allowance.
9. Using the 4 inch opening you left on the side of the inner fabric turn the fabric right side out.
10. Next match up the corners and iron around the top of the bag.
11. Now you are going to sew two lines to make the casing. The casing is what the rope will go through. Sew around the fabric (so starting and ending at the same point) from where the top of the hole and from the bottom of the hole. If you are using a waterproof fabric you will want to use a walking foot for this part if you have one.
12. Take one piece of the rope, attach the end to a pin and pull it through the casing to the other side, then keep going and exit out of the same hole you started at.
18. Sew the hole in the inner lining closed. You can sew it closed by hand using a blind stitch or you can sew it closed on a machine. The choice is up to you!
