I was bored and walking around one day, I took these and my husband said, "how do you even find this stuff?". I don't know, I just do.
Here are a few:
teeny tiny I almost missed it
This is like a spiny golf ball...love it
it was like a whole field, actually an area about 10 x 10
look at the underneath of this one, it's like lacy. My favorite
the top is about the size of a dime
another view of the lacy bottom
