I (and my mom) make cat toys and sell them! These are almost exclusively made from discarded materials that I get by dumpster diving. Any stuffing comes out of tossed pillows and most of the fabrics are cutoffs from my mom's sewing projects (she also gets a lot of fabric free or cheap from friends or at garage sales, etc.). Socks and other articles of clothing are also used.
We have been selling primarily at local craft shows, but I have added them to one of my websites and am working on marketing the website so hoping to start getting sales that way soon.
Here's a link to my shop page where I have all the cat toys we have for sale:

Including pictures of me at one of our craft shows and some sales we made where people paid via Venmo (including the one with the pizza emoji, though I'm not sure why the customer added that as the note). Most sales were cash, but I think I have enough proof here for this badge!
I don't have pictures of us making them, so please let me know if I need more proof and I can make sure we get pictures next time we're making products.
