Thickening a string- in a different way

Is there a way to make a string thicker- but not as thick as adding another rotation? I have a pretty good string at 8 threads in total and its already thick for its thread count. Of course, i cannot add half a wrap to result in 10 threads, but when i do add 1 whole rotation, the string is too thick. Is there a way to half wrap? Or make the string thicker in a different way but not as thicc as another wrap added? (Like, a fabric conditioner or something)

You can add a half-wrap - tie off the string at the other hook before reducing.


Half wrap or blend with a thinner or thicker thread.
