??-Shrinkie install on thin/fine hair

Cool, thanks for the feedback...I got about 130 strands in and so far the shrinkies are pretty well hid.  I did use 1/2 size on the top 2 rows and I'll see how they hold.  I plan on doing the cutting myself this time and bought a razor for blending, I bought something called a hair shaper that has a folding handle with a razor on the end.  Will that work?

I did the entire install myself this time and besides some sloppy sectioning and burnt fingers it wasn't to bad. 

I have thin fine hair, and I only fit about 120 strands in my hair.   If I used slightly smaller bits of hair, I could probably get to 150, but I have no idea how it would be possible to get 200 + in my hair unless I maybe doubled up the strands.

I'm wearing glued in wefts now, and for me, it's much more comfortable than shrinkies.  I think that's because I had to use so little of my hair to hold the shrinkie and the strand that it seemed to pull too much.  And, as thin as my hair is, when the wind blew, my shrinkies would poke out.
