peverel:

highest growing hair is a clipper gaurd #6. Hairpiece hair is pinned to a styro foam head then all buzzed to #8 clipper gaurd then the crown area and top head is hand trimmed with a 6 and 5 guard just to tighten it a bit. When attached, the sides are blended with a razor comb slowley with frequent checks to make sure to not take too much at once and the thicker parts of the unit are blended down where ever needed with the razor comb. The only problem that I run into is when the factory puts some hair around the perimeter flowing up instead of down. When you go short, these hairs are hard to get to turn back on there vented direction and this only happend because of the venting direction. You have to be prepared to use grip/texture gel on the hair when it dries and hand work it flat...it's always fixable with good texture gel.
