Aye, I usually use a pair of scissors to cut like the normal tabs and pieces out of the paper. When I get those tiny tabs, I use an uber sharp knife to cut it. Normally I use a ruler when it comes to the valley folds, and typically do the mountain folds by hand without a ruler. Depends on how the tab is and some other things. I typically use wood glue by Titebond. I find the wood glue works much better at securing the tabs to other pieces. It actually cures stronger than the paper :joy:
Normally, when I was using like an X-acto to cut pieces out, I would just free hand cut it without using a ruler. I found that I messed up on cuts more often free hand, but it works better with larger pieces/parts of pep. Using scissors is slightly less accurate than using an x-acto with a ruler, but it is a little faster for me to do.
