I did this for the first time this year from some very nice bell peppers I got from our local supermarket. I took the seeds out, wrapped them in a paper towel and let them dry for a few weeks and then planted them in a potting mix. Maybe eight seeds per pot at 1/4" deep at most and spread out. A few didn't germinate but I had six seedlings doing well if I recall correctly. They're coming along so far...

I'd like to start a habanero plant as well. Starting plants from seed is pretty addicting.
Good luck!
