I taught in MD through our local adult education classes---through what is sometimes called parks and rec. I had to make up the project and a proposal. The head of it helped me pick a location, time etc. The schools did not charge a fee or the agency. I taught 6 or 8 classes---hard to remember--and charged $50.

I LOVED it and eventually did an intermediate class also as the students wanted to learn more. I am thinking I did maybe 6 sessions before moving out of state.

I had been quilting maybe 2 years and the first class was all about buying supplies, etc. They could machine or hand piece.

I do not evaluate an instructor on his/ her age.

The National Quilting Association has a publication " teaching beginning quiltmaking". Check out their web site. Unless you are very confident in your ability, I am not sure it is a good idea. I would get some help from a quilter who would serve as a mentor. Have you had experience teaching.
