Making dowel joints is much easier if you don’t mind the dowels being visible. However, this type of joint can only be made if one of your pieces of wood is thin enough that you can drill all the way through it.
You will most likely need to use dowel rods for this type of joint, as dowel pegs are likely to be too short to reach all the way through one piece of wood and into another.
The dowel that you use should be a little longer than the hole you drilled.
Step 1 – Clamp joint
Clamp the two pieces of wood that you will be joining together in place with the thickest piece on the bottom.
