I have learned to fold like I do my regular laundry which is pretty much the same as the tutorial mentioned. I don't use a ruler but I get the same effect. I have categories. I have charm, fat qtr, then 1/2-1yd and up goes on comic book boards. BUT I have 1yd +, then 2yds +, then 3yds+ which are all wrapped on comic boards. The + is the extra piece attached. Depending on the + determines if it goes into the scrap bin. The + may be a strip that I need and is the right length. Works for me.
