Lol!! You are in the same postion that I'm in right now! I had sister lock but decided it was way too thin and let them grow together. DynamicRunner on YouTube website did this but let hers grow a bit then cut one of the "Two headed Dragons" off. I decided to twist mine as I always wanted thick lock but my parents have a bad attitude to "Rastas" ( anyone with locs are Rastas to them) I have just this week finished twisting them together and used brown thread then I had to us black thread as I put it somewhere safe and forgot where that was lol!!! I'm dyeing my hair red again this week as I have been using a clarifying shampoo to remove build up. I found you on Facebook while checking out some loc wearers. I hope you don't mind me coming on here. If you do, just let me know OK. many thanks Eve Alex from Facebook.
