We’ve had several requests for this pattern. My Mom gave me the pattern that she made from an antique hot pad that was found in a church basement. She took it apart to see how it was made. It’s double thick.
(If you would like to make a different size, measure diagonal across the size square you would like to make and make a chain that long before starting the rest of these instructions.)
Use a G hook and cotton yarn (nothing that would melt from heat)
Chain 36 (or more if you want a larger potholder)
SC (single crochet) in 2nd chain and all the way around chain with 3 SC at bottom of chain.
Working in back loop, SC 15 rounds. (If you chained more than 36, you will need to do more rows, test by taking the oval and shaping it so you can see if it meets in the center, see * below.)
Stop on side and slip yarn through.
Leave 12 inch tail. Turn to right side and fold into square.
(* sides should meet in the center if you have done enough rows)
Whipstitch edge together with tail.
