First, you should clarify the secret about the relation between Weft and bundles:

For Partial Sew-in

Partial sew-in is an adaptable choice when you have your natural hair but you want it to add extra volume or extra length to your hair. Regularly, 2 bundles are enough to give you a natural look, it also depends on the amount of hair that you have left out.

In case you just want length then anywhere from 8 inches to about 16 inches you only really need one bundle. Anywhere from 18 inches to about 22 inches you can get away with two bundles or one and a half. For anything past 24'', you will need two and a half or three bundles, so it just depends on what you're looking for in thickness.

If you don't like to do a partial sew-in, a U-part wig is also a great option. As it blends fine with your own natural hair which has a U-shaped opening on top, you can choose a texture that resembles your hair to make an integral hairstyle.
