The last DIY hair comb was such a hit that I had tons of requests for a step-by-step tutorial. I hope this helps! You wrap your floss between the comb teeth. You start wrapping the way you do each time you switch a color, start in the back and pull through the front. Hold the floss to the back while you do your first pull-through. When you come back around and pull through again, you'll have secured the end of the floss. Check the photos for specifics and how to end the wrapping.
If you checked out the last hair comb diy (see comb below - upper right & lower left), then you may have noticed that I wrapped differently this time. I think I prefer this method but they are both super cute! You could do so many variations with this. With the first comb, I wrapped until I finished a piece of floss, so I could wrap between two or three teeth. With the second comb, I would wrap only one space and cut extra length off before moving to the next space.
If you make some, show me some pics! Oh, also - I had lots of questions about how to do my hairstyle from the last diy comb (the updo above). I wish I could help you ladies but it's just works because I have curly hair! I didn't even look in the mirror to do that - I twisted it up like a french twist and stuck the comb in. That's definitely a benefit to curly hair - it holds any accessory and any style (other than straight!).
