How do I find antique furniture than I can refinish myself?

Research crags list.

Keep your eye on newspaper ads...watching Yard/Estate sales, miscellaneous for sale, etc. you can find cheaper antique prices this way.

Garage sales, thrift stores, Craigs list ( I don't like it). Local online sales sites.

Garage sales, yard sales, thrift shops, Goodwill. Check local newspaer listings. I am on "Nextdoor" a neighborhood email group and neighbors in the immediate area post all kinds of free stuff that is great for making over. I picked up a fantastic small wood dresser that was perfect for this type of project. I gave it to a friend to make over. There are a number of "apps" that have advertisements for items like this, but I am not an app person plus sometimes these people are a bit dishonest. If you go that route, know the neighborhood and take someone with you, even if you meet in a public place. Safety first!

So many people right in your church has an Item or two to get rid of sometimes just putting a notice up or an announcement brings you luck

There are websites called yardsalefinder.com, etc, and you can find local sales that way. A lot of people sell antiques at yard sales for very little money.
