I knew it would happen! As soon as I caved and bought a snowflake piece on eBay, look what I found in a thrift store:
A 1.5 qt casserole in white with turquoise snowflakes. For $5.00!
Admittedly, it was a charcoal Snowflake I bought on the 'bay, but I'm not going to complain- I love snowflakes! And I love this size casserole- it is perfect to heat up a rotisserie chicken or side dish.
This is actually my first oval Pyrex casserole- I have a Fire King one in this shape that I use a lot and am happy to have found another.
