started making the odd mecate a few years ago; have braided split lines for years....never had a problem, but one of the mecates i recently made has started twisting, and it appears that one of the colors (2 strands out of 12) appears to be shrinking next to the other 10 strands....it looks awful, makes the other 2 colors look like they are bulging.....i've made about 10 mecates thus far, no core, 12 strand square, solid, 2 and 3 colors, and i've never seen this before. this one had been rained on for a coupla days, and the color that appears to have shrunk was a new color i'd used, but it's from the same company i've ordered from for 4 years....i'm just sick about this, because it's a lot of work, and i don't have a clue what's going on....i've got split lines i made 20 years ago that are part flat and part square (8 strand), white originally, and they haven't gone all wonky like this mecate has. i use the 550 paracord from armed outfitters.com.
any ideas?
