The one I made was tied and not stitched, to make something that was the equivalent of a modern Superavanti in layout.
The two knots, one per side at the end of the waistbelt section to make legloops and maillon attachment loops were a little complicated, but there was a lot of incentive to follow the diagrams in the club newsletter and get them right, and they seemed to be nicely self-tightening.
If I remember correctly, the 2" tape was quite low thickness, and reasonably flexible/foldable, which made it easier to get neat compact knots than if it had been stiff or thick.
It did have to be tied the right size, since adjustment was pretty much impossible, but then, adjustment was close to impossible with a Croll, once it had been used a bit.
