This is one of the occasions when having good tools is essential. When I had eventually managed to cut the slots and started to insert the unprintable half-millimeter screws into unprintable holes through unprintable hinges, I discovered that my smallest screwdriver was not small enough so I ended up working the screws with my mini craft knife which was the unprintable of a job. I was exhausted when I finished and almost gave up on continuing that evening, but I had to reward myself for being so persistent.
Assembling the frame was easy.
Then came a step that demands dexterity and patience, but nothing like the unprintable hinges. Keyholes and handles for drawers - and I had earlier done this with the night stand.
I had to leave the assembled desk and drawers overnight to set.
Then I gave it a coat of varnish.
Here it is in the interior, with the top cabinet in place. Now I only need some teeny-tiny objects to put into drawers and pens and stationary for the desk top.
