I think Etsy is where he'd buy the knitted tea cozy from a lady in Vermont.

Up until a couple years ago, he would go to Ravelry to get the pattern to knit the cozy, but they went full fascist and banned any Trump/MAGA stuff from their site a while ago.

Pinterest is where he can (well, not now, but last week he could) either search for tea cozies to buy, patterns to make tea cozies, or ideas for decorating the dining room to match his chosen cozy.
