You'll need to take some measurements before you begin sewing to create your pattern. It's super easy. Measure the crotch strap's length and width (without the latching mechanism). Find a cup that generously covers the entire circumference of the latching mechanism when the cup is placed on top of it. I should have taken a picture of that step, sorry.
To make your pattern, triple the width of the crotch strap. Mine was two inches, so 2*3=6. This is the the length of your rectangle. The height is the length of the car seat strap plus .25. So mine was 1.25+.25=1.5. Alrighty. My rectangle now measures 6 x 1.5. Draw that out and find the middle of the rectangle by folding it in half. See my fold line in the picture below. Set your cup right on top of that line, overlapping by .25" in and trace it. Now cut that out.
|You'll need some bias tape and a 1" piece of hook and loop.|
I used some fusible hook and loop which worked nicely.
Although I ran into a snag when I applied one side to the wrong spot,
but I was able to pull it off. Phew.
|Grab your bias tape. One side is wider than the other, this side should be in the|
back so that you don't have to worry about whether you're catching the back when you sew.
|Start on one side of the circle.|
|And ease your way around. You can pin it, but I'm really lazy.|
In fact, I'm so lazy that I chose white bias tape just because
I already had white thread loaded in my machine.
|I sewed two lines because I'm rad.|
|Cut a little snip in the end of your next section of bias tape|
so you can butt it up nice and close to the circle.
|I have no idea with this is portrait orientation, but no matter what I do|
delete, re-upload, swear, it won't show up right.
Anyhoo, this is what it looks like.
|Super chub is safe.|
|And someone's happy!|
Again in hindsight I would have used a slightly
larger cup to make my circle bigger, but hindsight's 20/20 and this will work.
