I been watching videos about pipe cleaner curls all over You Tube. Check out Chescaloc's tutorial.
Why not try these on braids/twists? Same concept as perm rods/ flexible rods at a fraction of the cost. They are much more comfortable to sleep on. While testing them first on myself, I barely felt them. As an extra safety measure, I folded the sharp ends over.
MG2 has twists and MG3 has braids. The pipe cleaners yield tight curls and ringlets. I don't recommend trying these on loose hair--the strands may get caught in the twisted pattern of the pipe cleaners.
I purchased my pipe cleaners for a little over $1 at Walmart and made sets for us all.
