The step everyone skips is sanding between coats of joint compound, not just after the final one. Two thin coats with a light sanding between them, each fully dried, gave a far smoother result than one thick coat that always seemed to leave a slight ridge no matter how carefully I applied it.

Priming the patch before painting mattered more than I expected too. Skipping primer on a patch I did last year left a faint flat spot visible under certain light, even after two coats of paint, because the compound absorbed the paint differently than the surrounding wall.

Thin coats, patience between them, and a primer coat, that’s the whole difference between a visible patch and an invisible one.

Most wobbly chair legs aren’t a broken joint, they’re a loose one, and wood glue alone often just seeps into a gap that’s too worn to hold anything. Wrapping the tenon in a few strands of wood shim or even waxed dental floss before reassembling gives the glue something to actually grip.

I fixed three dining chairs this way that had been wobbling for over a year, all of them holding steady four months later with regular use. The whole repair took about twenty minutes a chair, including clamp time.

If a chair leg is loose again within a week of a glue-only fix, that’s the sign the joint needs bulking up first, not just more glue.
