Here is how I sew clips onto Infinity wefts which is a great way to add value to your clients extensions when they decide to take them out and/or if you just wanna give them a customized set of clip ins that will be super seamless and easy for them to put in! I definitely think it would be much easier if you clipped the weft to the head of a mannequin while you are sewing. The clips I am using can be found on my Amazon link in the highlights or in my Sarah Page bio.
