I always shake my head when people say they want to compost but don't have anything to get started. All you need is a place to toss your scraps! Sure, it's helpful to have a rotating bin, a container to keep critters out and other items but honestly you just need a place to put your scraps and something to turn them with.
We have a three-sided bin that we put together with pallet wood and it's worked for about eight years. We fill it with scraps, grass clippings, etc. all year, turning it each time. We don't add to it in the winter (we could easily add to another one but the chickens and dogs love the scraps!), let it sit, and by spring we have the richest, most gorgeous compost you've ever seen, perfect for gardening. Sometimes we even have seeds sprout out of it it we weren't careful with our veggie scraps!
Research your composting techniques all you like but there's no need to complicate it. Do you already compost? What is your method?
