I found a blog site on Pinterest this morning that had a recipe for shave cream and I dropped everything and made up a batch!  I love it.  She is so right, that is one product I hate spending money on!  :)

P.S.  I have just now finished up my first batch of homemade shaving cream and I'm planning to make another batch.  When I have that last little bit of product left in a shampoo, conditioner, or lotion bottle I don't feel so guilty now about not using every last drop. I know it will get used for this!  
I took a lot of teasing from my friends and family for making this.  A lot of shaking heads said "you know... shaving cream isn't THAT expensive.."  but I won them over in the end!!!
