foiling is realllly easy if you do your eye makeup in the bathroom like I do. I just run the water till it is warm, stick the brush head under the stream of water and add a teeny drop of whatever soap you use to wash your brushes.(this washes off yesterday's colors). soap it off and rinse really well. you are left with a damp brush. I like to blot it it a bit with my towel or I end up up wasting product.Shake a few grains of your e/s into the cap, or your swirly bowl and use your damp brush to make almost a paste of your eyeshadow. It's kind of a trial and error thing whatt exture works best for you, but I foil all my shadows and never get fallout. I always use the Stick-Em primer and never have problems with blending.
I also work from the lightlest to the darkest eyeshadow also.
I do my makeup in the bathroom now but am in the process of moving it all to a spare room with my new makeup vanity and cart. I will try foiling when I have time to play around. I want to take the time to practice and perfect. Thanks for reporting about the Stick-em primer; I had my hands on it today but didn't have time to play with it.
