This is my 1st instructable so please bare with me.
I always appreciate feedback so do your worst!!!
Thanks and enjoy...
Step 1: Items you will need checklist
A tape easy to work with (I chose Electrical Tape)
A flexible measuring tape
2 sets of standard male/female plastic connectors
2 Lengths of 1" nylon webbing straps typically used with the clips on bags
A length of 1" elastics
A GO PRO flat mount (not pictured)
A couple tubes of Super Glue ( In retrospect, I might have used a more workable adhesive like rubber cement or something)
A few pieces of paper used for the templates
For the main material you will need something tough, and something a strong glue will adhere to. That's important...
I used a 1' x 2' piece of vinyl canvas used in Cirque Du Soleil tents (it's weather-proof and bomb proof).
I would recommend trying to find this material, but I'm sure you will figure out something else that will work!
Step 2: Make your measurements
I measured my little girls front chest width stopping just in front of the arms.
For the back, I went a little further stopping at the arms.
For the height I just made sure it was low enough not to ride up her face when running and crawling and low enough for her to grow into a bit.
I laid it out onto a sheet of paper and made my measurements based off of the "center line" running vertically.
I took a notch out of the bottom on both pieces, and added a deep cutout centered for her neck.
I used a round object and guessed the radius's.
This photo is of the front piece.
The back piece was slightly larger so I added the 1/2 notches on the top and bottom, and made sure to KEEP MY NECK AND STRAPS CENTERED and the same as the front piece.
