Ninawa Zero-Waste earned its Boston Public Market stall by winning the market’s entrepreneurship competition, and the business is exactly what it sounds like: founder Aelen Unan upcycles discarded curtains, sheets, and tablecloths into tote bags, aprons, and kitchen linens, keeping usable textiles out of the landfill. This drop-in workshop, held downtown at the market near Haymarket, puts her methods in your hands.

You’ll settle in with the Ninawa crew and stitch a reusable tote from reclaimed fabric, with materials supplied and no sewing experience expected — the drop-in format means you come as you are and leave with a bag you made yourself. It suits crafty types, sustainability-minded shoppers, and anyone who’d rather take home a market souvenir that never sat on a shelf.
