Thanks for all of the suggestions so far. Sounds like once I get started I'll just keep finding more that I "need" to have.
And I love this sight...I found someone who was selling some Nestabilities and just bought 11 sets this morning! Hoping that I got a good deal by paying $95 (that included shipping) for them. I got circles small, double end tags, fancy tags, labels 1, labels 2, labels 4, oval small, scallop oval small, scallop square large, scallop circles small and squares small.
Any others that I can't live without???
Now I have to figure out how to hide the box from my husband when it arrives
