While the pandemic has struck a huge blow to many small-business owners, some savvy entrepreneurs have capitalized on a new and exploding market: facemasks. In Miami, the best-face-masks honor has to go to Martha of Miami. Martha has long made a name for herself as the quintessential 305 merch seller, and her masks follow suit. If 2020's giving you the heebie-jeebies, try Martha's evil-eye mask to purge all the bad vibes from your life. Or choose from styles covered with mango, piña colada or cafecito designs. There's even a trademark "Cuban Bred" version, so everyone will know what you're about, even from six feet away. The Martha of Miami store is open from 11 a.m. to 6:30 p.m. Monday through Saturday; all masks are $10 or under, with a balaclava-style full face cover available for $14.
