What is Repair Café?
Repair Café is a free event all about repairing things together. We have tools, materials, and volunteer experts who love to work on clothes, furniture, small appliances, bicycles, crockery, electronics, lamps, toys, and lots more. You can watch or participate in the process; it’s all about extending the life of everyday items and keeping them out of the landfill.
