Just wanted to share something.....So for instances where I don’t feel like they can support the weight, I will do one of two things. 
With her I used a JZ styles weft underneath because they are about 3-4 inches wider than Covet and Mane and end up going all the way around the head. Then I layered two C&M wefts on top. 
You can also put 2 Covet underneath by starting them in the middle of the head and wrapping around the sides, then placing one weft on top for coverage of everything. Does that make sense?
I usually go with the Jay Z styles route though because I don’t like to wrap corners.
