Wrap and Zap is out of stock on Walmart.com. I spoke to Michelle at Pellon who said that it has been shipped to Joann's warehouses but they have no control when Joann's ships it to their stores. Can't be found in LA area stores yet.

You really don't need to make so many marks when you make them. When I make mine, I layer the fabric and batting, then sew both ways on the diagonal to keep the layers together. Fold the block in half and mark the darts 1" x 2-1/4". Do this on all four sides on each block. Place two blocks right sides together. I don't clip the darts, just fold them to opposing sides. Sew two blocks together, leaving a 2-3" opening to turn right side out. Be sure to push the corners out as much as possible. Top stitch all around the bowl, closing the opening. It takes about 20 minutes to make a bowl. I use the "Wrap and Zap" batting by Pellon. I purchased mine at JoAnn's. It was regularly $7.99 a bag but I used a 50% coupon. This is also the batting to use if you make potato bags.

You can custom fit these to your bowls if you measure how high the sides are, and let that guide you in how deep and long you make your darts. Of course it helps to have a bowl with you to try it on for size as you create the bowl-holder.

THANKS for the laugh but I was thinking the same thing. We all have senior moments at one time or another !! My friend made me one and told me it was to be put on top to keep the microwave clean. I told her otherwise. They do really work well. Great idea to use up those scraps of batting.

If you google micro wave soup bowl directions you can get the directions.

Do these serve the purpose of insulating the bowl, or are they basically just a pot holder

I was thinking that, too!

You can reheat something in the bowl with the potholder in the microwave, making it easy to remove and not burn your fingers, by grabbing the potholder's corners. Then the potholder helps to keep the food warm while eating, too. These are especially nice if you are holding the bowl while eating (like in front of the tv, lol!).

Oh my, these are very nice. Need to make some of these.
