I finally made the clip-ins (don't judge me) and I am in love!!! It took me a minute to make sure that the clips were sturdy and wouldn't slip off. The material used was: a sewing needle, sewing thread, glamour house of hair, and 10 packs of clips. It took me and hour to make 5 tracks with two clips on one track. Althouh I am pleased with the outcome I am going to double up the two clips in the back so that it is fuller.
