I've been doing this for years - someone on here told me about it - maybe SuZen??? But I use the long plastic clips like this: http://counterculturebeauty.com/wp-c...hair-clips.jpg

I have cheapo ones from Sally's.

My hair is fine and thin so I diffuse the ends first and then hang upside down and do the top of my head. After diffusing, I run the clips in from the front towards the back of my head. Depending on how my hair looks, I may use just one that holds the 2 sides of my messy part together so it doesn't go flat. Other times, I will use several on either side of the part to get big hair all over the top. I love BIG hair but my fine hair will rarely do big but if I didn't clip on top, it would be totally flat.
