I just wanted to pass along my composting method (as well as get your thoughts on how I can improve it). I don't have a bin or tumbler. What I do have is time. The method I use takes 18 months to start producing compost, but once you start, you'll have fresh compost every spring.
In the fall, collect your leaves (I collect them with my mower -- shredding and bagging them at once) and put them in an out-of-the-way location. Throughout the year, add kitchen waste to the pile (no animal products except for egg shells!), turning the pile from time to time. I also add grass clippings from time to time (I typically don't bag the clippings -- I mulch them into the ground when mowing the yard).
After 18 months, your leaves will be converted into compost by your friendly neighborhood worms. Sift the compost through a sifter (I built a 2'x2' form w/ studs and 1/2" steel netting) to remove the larger pieces (this also breaks up any clumps) and spread it on your garden. Believe me, your plants will love you for it! Make sure you start a new pile each fall so that you'll always have a pile going.
