I always end up with a bunch of very slender wood from branches and tops. When I drop a tree I take EVERYTHING burnable out of the woods with me. I split everything "hotdog thick" and up, and mix the slim stuff int the wood piles. It's great for filling in between larger pieces in the stove, as well as for having smaller fires when it's warmer. You can get a surprising amount of heat from a stove full of 1inch thick limb wood split, and it dries incredibly fast.
