How to dye Doll's Shoes/Cómo teñir Zapatos para Muñeca

Nancy dolls have a wide range of color shoes, but some of them are so pricey that, at least to me, are unaffordable. So, one day I decided to try and dye them with acrilic paint, adding a coat of varnish (for manual arts), and I liked the result, but the next time, I tried it out with nail polish and it looked even better! I bought these you can find at 99-cent stores, and it worked out pretty well.
