i think ur describing how I've been wearing my hair the past 6 mos (i could be wrong). I use the longer Marley braid hair (femi brand). My twists are not tight and everybody compliments me on my "real hair" but I usually tell them i've added exts. I don't have any updated pics. It has taken me a few years to perfect this look as I braid it myself.
ETA: Duh, if you click on my blog link you will see a few pics of twists...although,I've redone them since my last post and they are now a lil past shoulder length.
