Finished retightening last night! Here I am with my retightened sls, looking a little tired, but VERY HAPPY!!!! I actually enjoyed doing it. To think I'd been dreading doing this all along. The sense of acomplishment is..... marvelous. That metal yarn needle is THE TOOL! So easy to use. I did it in 4 days. I think I spent a total of 6-7hrs, which for a 1st timer isn't bad at all. Folks, I took NO CLASS. I learned to do this from various blogs, tutorials and youtube videos, and encouraged by other DIY-ers. Nubianlockedprincess, Cheleski, dewdrop, saabira to mention a few. The rotations were very similar to what I already learned from the bradelocs e-bk and Nappturality. I had to acquire a little more skill bc these locs are MICRO! Keeping locs out of the way of the one being tightened is CRUCIAL to success.I wanted to stick to the 3pt rotation used by my loctitian and I did... except it was in reverse. If you're determined to DIY your options are to take the Official sls class, which will cost a few $$ or research interlocking methods and take it from there. If you don't have the time to research and practice, you have $$ to spare and a class near you and you're a sls purist then just take the class to be safe. You will still have to practice practice practice. I'm glad I do not have to fork out more££ to learn something so simple. Having said all that,I'm not actually new to DIY-ing locs, I used to maintain My Bradelocz some of the time, (with a nappylocs tool)but doing Microlocs Myself was another matter. Now that I've cracked this one, I shall visit my loctitian only when needed so she can look over what I'm doing and correct any mistakes. My RT shoulder is a little sore from holding my arms up, otherwise ALL is WELL. I am well pleased to finally join the ranks of DIY. It's all looking GOOD, even if I say so myself. Not to mention £50 saved towards my Ghana trip. Now, this is what I call Freedom. Hehehehe.
