Protect your hands from getting burnt when holding a hot bowl of soup or oatmeal....Make a bowl "pot holder" to protect your fingers ;) You can use Warm Tater Batting (seen this on pinterest and its for microwave use). Also make sure to use cotton thread and not polyester.
I made the following sizes and here are the size darts that I used for each:
15 " x 15 " size bowl holders: I used 1 " across and 3 " down for the darts
12 " x 12 " size bowl holders: I used 1 " across and 2 1/2 " down for the darts
10 " x 10 " size bowl holders: I used 1 " across and 2 " down for the darts.
I had a subscriber use : Pellon's Wrap N Zap batting that is 100% cotton and it seemed to work well for her.
