If any of you are planning on doing your own clip-ins here are few tips I found to be helpful : Before cutting the weft of hair, measure where you will be applying the extensions and then cut. Buy thick thread (doesnt neccessarily have to be made for extensions, any thick thread will do) it holds better and can withstand hairspray. Make sure your clips are facing downwards and closed before attaching them. Insert the thread in the clip first, then sew it into the weft (it's a lot easier this way) Sew in the two holes that are on each side of the clip as well as between the teeth of the clip with tension and make a knot at the ends for security. The clips should not be sewn in at the very ends of the weft, leave a little (very little) of the weft hanging over the ends so the clips do not show. If you plan on wearing your hair curly/ wavy buy hair that is already a bit waved, the curls will last longer. Have fun and do this with plenty of time so you can test them out before your big day
