I had a very similar issue. Only thing I could tell you is to start letting them congo around the bald spot. grab a few that are close together, but on different side of it, and put a bead on them. If it hasn't started to close up in a few months after stopping crocheting, it might be time to take some action and force a few to combine.

actualy crochert recovery can take over 6 months so if its only been a couple give it more time

I love fatties. I've got a bunch of them, but If they are really that fat already, you might want to ask Eagle if it's worth looking into using a razor blade to split them apart. Once they are thinner they might fill in that space too. I didn't realize they were already big

instead of combinning 2 fatties into a mega fatty sencourage loose hairs to form several thinnies betwen fatties this makes it more blended a more full look u can have 3 massive fatties and seem like huge gaops between or 400 tinies with no gaps betwen (unless way over tightened like sisterlocks)

but if its thin next to thicj=k next to medium they tend to blend fill in gaps and look great

let em recover from crochet mor and seoerate as koose hairs appear in the gaps the loose hairs fill the gaps with soft hair thwt then will become new babvy dreass and solve the problem for good

i have the same problem.. i think it's from over-maintenance. i let someone else palm roll the HECK out of one of my dreads, and i've been able to see my scalp ever since. and it's been at least 6 months. perhaps just give it some time? how long as it been since you've crocheted?

Isnt that like the center of the spiral on the top/back of your head? My hair naturally falls away from that as well and so I let those be sections around that but as they locked up I found that to be irritating and overly sensitive so I grabbed one on each side and joined them. It'll be a fatty but at least that weird hole and sensation is gone
