I think I might have found the most awesome thing in the world!
Thanks to my superb sewing skills and some free time where I had the house to myself, I finally managed to not only sew some cloth diapers but also actually try cloth diapers out for the first time.
I wore them for almost 3 days exclusively, and it was possibly the best thing ever. They were so warm in this cold weather which was nice and I was surprised to find that even with three or so layers on, plus the plastic pants, they weren't at all bulky or stopped me from doing anything I wanted to do, even going on a bike and running.
I'm planning now to make some all-in-one diapers so I can wear them more often and a bit more easily than the fiddly safety-pinned ones I was wearing.
Either way, I'm a cloth convert!
