Here's a link to the "easy" thread that OP mentioned: https://4-ch.net/4ch.html

Yesterday I made my own Lasagna Sheets by making dough and rolling it very thin. It was surprisingly straightforward and tasted great, though I'm not sure it was much different than using store-bought sheets. I used one of these those hand crank pasta rolling machines though, so that probably took out some of the hard work.
