I started out years ago searching for vases and discovered that EBay was a phenomenal way to add substantial pieces to my collection.  Now, I discovered beaded jewelry making and search for interesting beads and buttons.  My latest frenzy has been buttons.  I had no idea there were so many unusual and beautiful buttons to choose from.  Some that I've bought, I'm just keeping for my personal collection, others will be worked into jewelry pieces.  I am not sure if I'll ever offer my jewelry on EBay, however.  We'll see.
