This is a great place to start if you aren’t sure what sizes you want. I like to think of this as the “starter pack”. You’re going to get my favorite size (the most popular of all sizes) the 12 x 12 which covers a pie dish, a sammie and bigger bowls. You also get an 8 x 8 and a 9 x 9 which cover most veggies and cheeses and smaller bowls.
