If you're using basic tools like me, the simple best piece of advice I can offer is the above.
Last night I decided to make a simple TT isolation plinth. Literally a rectangle piece of ply with 4 sides to make a shallow box.
I cut 2 of the sides to completely the wrong length and because I rushed, they were all a little bit different in height +/- 1.5mm
I've glued it all together anyway and it looks like one of Homer Simpsons projects.
DO NOT RUSH

It's the old 'Measure Twice, Cut Once' rule I guess...
But at the same time, don't let them "mature" for too long. It can be hard to remember what you were doing after 2-3 years or why you were doing it.
Possibly a bit harsh, but hey.Please, come see my lovely plinth. If it not success, I will be execute.
