You can really skip the whole paper towel thing and just put your seeds directly into small cups* of pre-moistened potting mix (preferably seedling mix). Put the seed in a shallow hole in the center of the pot, not much deeper than half inch, cover, water. Just use a small bottle of water and your thumb to drizzle water on the surface, until the soil is just about saturated.
* With holes for drainage.
They need to be kept at a temperature from about 72-82 degrees for the seeds to germinate promptly. You could just put them in your grow room under lighting, particularly if you are using fluorescent tubes such as a T5 fixture. These can produce just enough heat to warm the soil surface up sufficiently. Keep the soil surface\pots about 6 or 7 inches or more away from the lights depending how warm the room is and how warm the lights get.
Heating mats are sold for seedlings/clones to warm the media 10-20*.
