COLLECT HISTORY: BUTTON CLUB SWAP AND SHOPButtons are a fascinating way to explore history, so much so that buttons are in collections of museums including the Smithsonian. Not only do they reflect changing fashions and innovations in materials, like the use of plastic, but it was very customary for historical events to be commemorated as tiny paintings on buttons. You can discover the hobby of collecting buttons at the Tampa Bay Button Club's Swap and Shop on Saturday. Here you'll find a range, with some buttons going for as much as $300 to $500 each, and then some for as little as 10 cents. How neat it would be to learn the history behind the antique ones? The free event runs from 9 a.m.-1 p.m. at Park Station, 5851 Park Blvd., Pinellas Park. (727) 742-5584.[MELISSA LYTTLE | Times]GREEN DAYS: GREEN THUMB FESTIVALDid all the Earth Day festivities last week leave you inspired to grow more plants? You’re in luck.
