I never make lace front wigs for other people because it takes an insane amount of time to hand-tie all those single fibers to the lace (to create a natural-looking hairline.) Ready-made lace-front wigs, on the other hand, are expensive and offer limited color and styling options.
However, the (non-lace) wig I originally ordered for this commission didn't arrive in time, but I still had an unused lace front wig in a different shade of brown, so I tried to make do. It turned out to be a lucky coincidence, because the color blend and the lace front make the wig look a lot more authentic IMO!
