I wish I could I join this challenge, but I can't because I'm doing the wig challenge.
However, I have a tip for you ladies. I rollerset my friend's relaxed hair this weekend and tried the idea below for the first time and it works. (I didn't remember to take pictures until after I'd removed the rollers. Next time I will.)
The tip:
When using mesh rollers, use slip-in hair clips instead of the pins, which can be difficult to master. (Slip-in clips are the metals clips you usually use with magnetic rollers, see image.)
Note: Mesh rollers are great because the hair dries faster. It's important that the "mesh" is good quality. Sally's sells the best mesh rollers (IMO). They are covered with a stiff plastic-like material. The mesh rollers that I saw in the BSS were covered with a thread-like mesh that wasn't firm enough to keep the hair flat and smooth.
