Place the vinyl record in the middle of your oven.
Don't let it melt. It most be hot but not so hot that the vinyl melt.
When its so hot that the vinyl is very soft and shapeble take it out of the oven. I don't use oven mitts but if you don't want to burn your hands please use them.
Place the vinyl record on a up side down bowl. Shape the record, you can do that a s long as the record is hot enough. Not ready and the vinyl record is to cold to shape? Put it back in the oven for about 30 to 60 seconds than you can reshape it easely. Made a mistake? Just put it back in the oven for a while, and then reshape again. :)
You can use this bowl for serving potatoe chips of candy or fruits.
Ofcourse I use mine for fabrics. :)
