Pull direction
You can apply the paste against the direction of the hair and then pull off with the direction of hair. (This is how sugaring should be done, without strips. It also hurts less this way.)
It takes some time to learn how to apply it right but keep trying!
I've read elsewhere about the various sugar stages and what stage you should heat your sugar mixture to. From what I read, you should heat this until the "hardball" stage. You may, however, be happy with heating it only to the "firm ball" stage.
A "cold water test" is handy if you're not a candy-maker. http://www.exploratorium.edu/cooking/candy/sugar-stages.html
Also, I have made this with vinegar in the past. It smelled very strongly like... well, vinegar. Not the most pleasant. Think of a large diffuser.
On a side note, it did work fine.
