Hello and welcome! Love your hair colour!
I was thinking more along the lines of letting the first one start to lock up before starting the second.
And my hair is extremely fine, and with twist and rip, the only way it would stay was by knotting into big loops and it was really uneven, and was hell to get out. It might work now if I tried since my hair is really dry from being backcombed, but I really like how the backcombing turned out instead.
As you can see I combed the front bit out... 10 dreads, took 10 hours :O. A couple of dreads were always hanging in my face and I got really annoyed at them.
