What's the longest length wig you can make?
Now that we have discussed that part, we want to bring up another issue: workmanship. It's difficult for wigmakers to ventilate very long hair. Sometimes, it breaks as they are pulling the hair through, after making the knot, it requires substantially more time to make the wig, and there's also some risk involved. When going for a super long wig, you may want to consider other options. We recommend using a blend of hand knotting, around the hairline, at the front and top, and machine wefting in the back. We also suggest looking at a fine mono cap, throughout the crown, so that the weight of long hair isn't pulling on the lace. Keep t he lace limited to the hairline area, and the first 2-3 inches of the wig base, for a natural appearance, then use a combination of other workmanship techniques, and cap construction, to achieve durability and practicality.
For obvious reasons, we recommend using uncolored hair, but if you must color it, stick to darker shades. Very long hair is older hair and may not hold up well to lightening to shades of light brown, red or blonde, especially the last 12-18 inches.
