For the wood suppliers, you will email or bring them the cut sheet that comes with the KIT itself. They will cut the 4x8 plywood sheet down to size for you for a few bucks a cut. You can then go and pick it up, bring it home, and do your assembly. Since plywood generally comes in 4x8 sheets, you can look for partial sheets (depending on availability), or you can look at building a KIT Family to use the whole sheet and have a matching set of KIT pieces.
1: LOW/ MEDIUM QUALITY WOOD ($-$$)
If you're on a budget or like the textured aesthetic, the most simple and inexpensive wood option would be to use OSB (top image) or Plywood (bottom image). Both of these would be available from any big box home improvement store or a nicer wood supply shop, both of which would be able to make cuts for you. With some sanding and sealing you can get a nice smooth finish, despite the roughness of the material. You can also use paint, stain, and other finishes to add some color or texture that can really make these more inexpensive woods have a beautiful finish. Get creative! Look around for examples of these inexpensive materials being used in creative ways.
2: MEDIUM/ HIGH QUALITY WOOD ($$-$$$)
If you're interested in using a nicer quality plywood with a more consistently smooth finish, you can look at a Birch or similar type of veneer plywood which can be stained, painted, and sealed to have a very high quality finish. The nicer Birch veneer has a more fine grain, and is generally a bit more smooth than the plywood and OSB. These styles of veneer plywood can be a nice middle ground, and are similar to what you would find in very nice cabinetry and solid wood furniture. You'll probably need to look for a local supplier (see the preferred supplier map below) who has this type of veneer plywood, most big box retailers won't carry this quality of wood. Many of these suppliers may have partial sheets if you're only building a single KIT, but if you're looking to build a whole KIT Family they can help you with cutting the sheet down according to our cut sheet dimensions.
3: HIGH QUALITY WOOD ($$$-$$$$)
If you are interested in a high end finish, Walnut and other plywood veneer styles can be a great choice. You'll see many classic furniture designs built out of these veneer plywood materials, and it will truly be a piece that you will want to have forever. You'll have to go to a wood supplier to find this kind of high quality veneer plywood, but this kind of supplier will be able to help you with the cutting and will generally be very precise. Check out our growing list of preferred suppliers below. The cost of these more high end plywood is quite a bit more than even a Birch plywood, but you sometimes can get a half sheet that a supplier has leftover or other smaller pieces that would work for your KIT project. If you choose to build an entire KIT Family, invest in a full sheet and enjoy the high quality pieces that you'll create!
