I guess there are numerous ways to do it, and hopefully you'll get a good number of replies so you can decide which way will work best for you. I use a nylon stocking (yes a women's stocking) and weigh it down with a stainless steel nut. I attach it with plumbers teflon tape by tying it to the nylon and slipping the other end it under the lid. That way I can remove it if I need to. Others have reported using a hops bag or stainless tea ball as well.
