Hey there. Upart wigs is something that looks like a sewin. It is more flexible to have because you can have your weave in this week and have it out next week. But making or installing one is all in how you measure for it. It does take practice but its best to measure your head from around the perimeter, front to nape, and ear to ear. Put the cap on your head and mark where your braid will be that you will sew the cap on. I have a vid on my uparts and how to measure for a upart. Check out my channel.
