Carpentry & Trim
Trim, framing, and repairs that look original.
Carpentry & Trim proves you can cut, fit, and fasten wood accurately — baseboard and crown that closes tight on out-of-square walls, framing repairs that carry load, and rot repair that stops the problem at the source. Everything below is free — no login, no paywall. Work through the skill areas, drill them in Study Mode, and when you're ready, prove it with the certification exam.
