Rubbing sugar into butter makes my hands feel fantastic. So I'm going to totally agree with Ange.
For under $10 I can get my hair cut, but it takes a while at the local beauty college.
DYI Eyelash tinting. Blue/Black, and really nice to do. I recommend doing it when you have time, away from little ones though. For $12 I can do this ever 6 weeks (if I get a chance) for a year.
A little powdered milk on your hand is a wonderful cleanser, just add a few drops of water in the shower.
My penny pinching facial. Milk powder cleanser, followed by a steam. Open up pours with a bowel of hot water with rosemary added & towel on head. Then a face mask I make around every month or so is honey with a few drops of orange juice. Left on for a hour, then removed with a face washer and warm water. I then put a little night cream on (Aldi brand I think it is around $8). Leaves your face feeling great.
Baby wipes are really good at removing makeup and mascara.
That is all I can think of right now. Great thread. Interesting read.
