These photos are amazing. I didn’t know you could decoupage shoes! If you want to find a tutorial for that just Google “decoupage shoes.” It looks pretty time consuming & I don’t know how long they would last. I don’t think I’d wear them in rain or snow! Some people use them as art objects.
Click title for link to many photo thumnails of decoupage projects. Some people are so talented!
I have heard of girls spray painting their shoes silver for prom to match their outfit. How about a pair of old shoes (your own or from GoodWill, etc.) painted red with acrylic paint & then topped with red glitter for a Dorothy costume a la The Wizard of Oz? I hear that acrylic paint stays on leather pretty well if you just want to change the color. To glitter shoes, spray with glue & sprinkle on the glitter!
