Buy a 15 gallon wash pail from Lowe's. They are only $15. Get four bricks as well for like $0.77 each, so about $4. Put the bricks inside the pail. Spread them out flat, to cover the bottom of the pail, and then set your logs on top of the bricks. This allows for airflow under your logs to keep the fire going. Then I used the Duraflame logs because they stay lit for 2 to 3 hours and they don't smoke as badly.
They look cool and are great for sitting outside in the evening and for evening parties, especially if it is cool out. Plus they are pretty inexpensive to make so you can do serveral. Place them around your pool or around the yard for a neat look, lots of light, and warmth too.
