Kimberly I think your set looks great! I don't think it's too tight. You're such a cutie.. those dimples!!
About pin curls or sets coming out too tight.. remember that everyone brushed thru their sets after taking the rollers out, there wasn't much "finger styling" or loose, spirally curls back then.
Mine is super tight after taking out the sponge rollers. I brush it the first day once, but tend to leave it alone so it will last longer later! I can get 3-4 days out of a set.
Another tip is to be sure you're rolling the same amount of hair on each roller, and don't twist or spiral the hair onto the roller. The ends should always be wound smoothly onto the roller first. As you're rolling the hair up, rock the roller back and forth *ever so slightly*, this will help it roll evenly and without TOO much tension. Again, perm papers help with this!
