Sea salt spray
is that how you avoid tight roots? If so, that makes a lot of sense. Also it makes sense that the dreads end up the size of the section. There's a grad student in the physics department of my uni that uses wax. His sections are like twice the size of his dreads.
do you count time starting from when you combed out your crocheted locs? Yours look better than mine in my opinion. I would have kept the old crocheted ones and just gone natural from there, let the knots build up, and then once the natural neglect part grows long enough, cut off the crocheted part. I almost took my brother's offer to pay to have mine crocheted but I want the bragging rights of saying that mine are freeform.
