The first card has been assembled. It’s just going to be a trial run, but it took me almost half an hour and it’s much more difficult to assemble than expected. This is especially the case since I have to do this at home. The lighting is much worse than what I am used to having in any of the studios at school.
The assembled package, including an envelope, measures almost 3 mm.
This is just a trial run and one of the things I had to test was tearing off the perforation. It was much harder than I expected. I should have tested perforations with the same paper stock.
Stapling the first signature also turned out to be much harder than expected. It would have been much easier if I had access to a proper studio. Alas…
Now a new question: Would this be too heavy for regular postage?
