Machine embroidery. Specialized items (towels, pillows, tote bags, wallets), teaching (classroom instruction and one on one), specialized services (machine maintenance instruction).
I started machine embroidery 3 years ago. Decided to add events like craft shows to my hobby. While at the different shows, people would ask me about teaching them how to use their machines. They would buy there machines from retailers that didnt offer lessons and they needed help. Seeing a need I started to help them. So now I go to craft shows and festivals and I teach people how to use their machines.
