An Indianapolis-based nonprofit that creates wallets, handbags and backpacks from reclaimed materials is launching a nationally-focused line of products for the first time. People for Urban Progress, which sells hand-made items from materials including the fabric from the old Hoosier Dome and signage from when Indianapolis hosted the Super Bowl, is repurposing leather from the seats in Amtrak’s Boston to Washington D.C.Acela Express trains.
