I looked for slipper socks at a couple stores and was surprised to find them pretty expensive, or at least to me they were, but then again I'm pretty cheap when it comes to such things. I thought about scrapping the idea of having them in my hospital bag just so I didn't need to buy them, then I thought "why not make some myself?".
So I dug out some puff paint and a couple pair of socks.
Flatten the bottoms of the socks.
Please ignore the fact these have stains on them, I swear they are clean, just old.
