Cutting joint after joint isn’t the best way to learn.
At least not in my opinion. After a lovely sunny, Sunday afternoon, all you’ve got to show is twenty-odd, randomly dovetailed corners. Some neat, some shite, some alright.
You’ll sit and think about these twenty-odd dovetailed corners, and you’ll realise, ‘I could have had a few boxes made, ready for use’.
If you’d made the boxes then you’d have also broken up the repetition with other jobs, like ploughing a groove for the bottoms.
