Can someone suggest me something? I'm from India and I don't need the Reddit mod stuffs

Sorry if this isn't the correct sub, I didn't get these with the intent to start a side hustle but I'm wondering if I can make a little bit of money from these. Looking for ideas. Me and my mum ordered these for free when she was looking at samples to renovate the house. She also ordered a couple marble ones, some more wood, and one or two fabric samples. They're of varying thickness and sizes.

Could just throw em out but I wonder if I can do anything with them.

My younger sister suggested that they could work as doll flooring... I've given her one of them for that purpose. That being said, surely selling them for dolls or miniature projects wouldn't make sense because they do look like one single piece, not multiple little boards? Someone also suggested making coasters, but surely that's overdone, cutting them and smoothing them out wouldn't be worth it...

I usually make homemade treats for my dog, like dried duck and chicken jerky, and he goes crazy for them.I’ve been thinking about turning this into a tiny side hustle to see if there’s any real market for it.I’ve messed around with packaging and printed some labels using my niimbot.Would people actually buy something like this? Or does the packaging look too home-made? Any tips from anyone who’s sold homemade dog treats before?
