Anyway, here was the outcome of my first attempt at a QSFW:
This is the diaper unfolded.
As you can tell by the picture, I opted not to add snaps or velcro and will be using my snappi instead. This way I can customize the fit better (and eliminate a step in the sewing process!)
Elastic for the legs to contain poopy. I wasn't super happy with how my elastic casings turned out, but hey, I'm still new to this :)
The only materials used to make these diapers were an old bath towel, an old receiving blankie, and some thread. It literally cost me nothing to make (well unless you calculate the cost of thread used and the cost of the towel I bought like 6 years ago, the blankie was a gift...but I didn't because that seems silly).
