Hairloop
A hair loop is essential to put your feathers in your hair.
You put your microring which is processed at the top of the hairwrap around the loop, then grab a tuft of hair to which you are going to attach the feather.
You put the tuft of hair through the loop and now grab the hairwrap and microring again. Now pull the tuft of hair through the microring with the hair loop.
You can now slide the microring up towards the scalp, insert the top of the feather between the micorring and pinch it very well with pliers.
