One of the most important materials in Animal Crossing is wood. Wood can be used for a variety of things, from building houses and furniture to crafting tools and decorations. If you're running low on wood, or just need a lot of it for a project, here are some tips on how to get wood fast in Animal Crossing.
One way to get wood quickly is to simply cut down trees with your axe. This will give you one piece of wood per tree, so if you need a lot of wood it's best to focus on cutting down larger trees. You can also use your shovel to dig up stumps after cutting down trees, which will yield one additional piece of wood.
Another way to get wood is by chopping down fruit trees with your axe. This will yield three pieces of fruitwood per tree, which can be used like regular wood but is also worth quite a bit more when sold at Nook's Cranny. Fruitwood can also be used to craft special furniture items at the DIY workbench.
If you have access to the island storeroom (unlocked by completing certain tasks), you can purchase large quantities of wood from Timmy and Tommy every day. The prices vary depending on what type of wood you're buying, but it's generally cheaper than purchasing smaller amounts from Nook's Cranny. You can also find occasional bundles of lumber being sold by traveling merchants that wash up on your beach from time to time - these usually contain around 10 pieces of wood and can be purchased for a discount if you haggle with the merchant properly.
Finally, don't forget that balloons occasionally float by carrying gifts - one gift type that appears often is bags containing 1-5 pieces of assorted woods inside them. These are great for topping off your supply if you're just short a few pieces here and there.
