I made hotpads like that one year. I just made a pot holder with 4 squares and quilted with an X. The back was made like an envelope for a pillow and birthed. Then I made a little muslin bag and filled with cinnamon potpourri. Slip the little bag in the back and the hot pot heated it and the smell came out. Remove the little bag for washing. After making them, I thought. What if the cinnamon doesn't really go with the food they are putting on the hotpad? Well they can remove it. Not like it fills the whole room. I bought, but haven't made, coasters made like that too. Figure the cinnamon goes with tea better anyway. Gave them as a gift. The recipients brother saw them and talked about them the whole time he was there so she gave them to him when he left. Still haven't decided how I feel about her giving away the gift I gave her.
