When I was home for Thanksgiving we made our own lip gloss! Of course, this was inspired by a pin I saw on Pinterest.com. It's really the easiest thing ever; it only requires 2 ingredients!
Kool-Aid and Vaseline Petroleum Jelly
You melt the Vaseline in a microwave safe bowl in 30 second increments, stirring in between each time, for about 7-8 minutes.
Once it's melted you add a packet of Kool-Aid. I think next time I will add more than one packet. It sort of changed the color but you can't really smell or taste it! Use a funnel to pour it into whatever lip gloss container you find.
I bought mine from RusticEscentials.com.
Over all these ended up being about $1 a piece including the Kool-Aid packets (we used Black Cherry and Pink Lemonade), Vaseline and the lip gloss containers.
Original idea from Meet the Dubiens.
