A service that you can offer if yours is the manual skill is to make custom-made handmade products or accessories.
Among them, you can make pottery, scented candles, incenses, hair accessory, jewelry, etc.
Another service you can offer is the preparation of invitation cards for special occasions or personalized certificates.
This is a job that obviously requires knowledge in the art you develop and manual talent for well crafted pieces.
You can do the job on demand, 100% at home. The only external work you can possibly do will be to buy materials and coordinate delivery.
