Why are you still taking the class? It looks like you have it down
For me, since the SL's are a trademarked locking technique/system I feel that I should respect the integrity of it. I have made the commitment (mentally/financially) in my SL's so I feel I should learn the proper way to retighten my locks. Plus I feel that since I haven't had them even six months yet (a few days away though) that I should just make sure. Although, I do have the technique down from the wealth of information given on the web and it will get easier and faster as time goes on, but there are two things that I know can change from using the NL tool to the SL tool. For the NL tool you have to:
1. Thread the NL tool (for each lock)which is time consuming.
2. You actually have to pull the NL tool through the new growth for each turn.
3. As my locks swell from locking I may have to purchase the larger sized one.
With the SL tool or even the latch hook you don't have to do the first two things. You push the tool through the new growth wrap the lock around it and then pull through like crocheting (lol) which has to be much faster. Even still after taking the class I will have the option of using either tool and I will be 100% certain that I'm doing the correct pattern and rotation for my hair.
Whats your thoughts on it?
