Mustard seed necklace

This story happened about 10 years ago. It was my second Philadelphia Museum Craft Show, it was all going fine, and first thing in the morning after the preview party evening, even prior to the opening time...so it was quiet. A woman walked past my booth, didn't even come into my area. As she passes, she said... you should put a mustard seed in them. 

And just kept walking......

So finally, I did. 

If you don't know , just google "one mustard seed'
