The KEY is to really keep an eye on them in the oven and be ready to use your hot mitts to shape the sides. I found a great tutorial on this site. I did make a few modifications.
1. Preheat your oven to 200 degrees. Turn the bowl upside down on a cookie sheet, and balance the record horizontally on the base of the bowl. When the oven is hot, place the cookie sheet, the bowl, and the record inside the oven and set your timer for 8 to 10 minutes.
I needed the full TEN minutes to get the plastic pliable. Keep in mind, that everyone's oven is different.
2. After 8 to 10 minutes, the vinyl will start bending down around the bowl. The vinyl cools quickly, so you'll be able to work with it immediately, but don't forget that the metal bowl and cookie sheet are hot! USE OVEN MITTS!!
3. Shape the edges however you'd like; more precise folding will give you finer scalloped edges. If the vinyl gets too cool to mold, just stick it back in the oven for a few minutes.
4. Wipe out the bowl (you might want to line it with a decorative napkin...but we live in the edge) and fill with your favorite snack.
I'm not quite done with our Justin Bieber party decorations.
