I already made a normal loop before seeing the tricky side, and I didn't want to start a new loop so I used my regular loop and put two sides really close and just knotted them in the right order. For the first 15 mins I regretted everything and wanted to quit doing this one, but I didn't end up messing the beginning at all!! it looks pretty normal now so if you also can't figure out the specific loop, a normal loop may work for you as well 🎉
@_Aurora_ you fold the strings that are only on the left in half and you pull the strings that are only on the right through where you folded it. That way both halves are connected and secured. I think MashaKnots explains this in her video on loops with an uneven amount of colours.
