I had the 5 pieces of the drawer, shown in the last step.
I also needed some quality wood glue, which I happened to have on hand from a former project.
And one needs a clamp of some sort, since the wood glue works best when clamped during drying.
I happened to have a "strap" clamp. It consists of a ratchet and a strap. Once wrapped around the area to be clamped, one "ratchets it tight".
These clamps are VERY handy, but are a bit of a pain for smaller jobs. They are great for the monstrously large clamping needs, without going out and purchasing special corner clamps, etc.
