I use a scrap piece of cardstock to smear the glue in a thin layer
I take my heat gun and I heat the glue. It will bubble and pop. I heat it until the glue is transparent.
When it cools it looks like this. It is shiny and has texture. It feels a little like leather.
Using black stazon ink, I stamped the leaf over the layer of dried glue. I used the leaf from Mark's Finest Papers set called AUTUMN GLORY.
To add color to my leaves, I took an acetate report folder and I scribbled with "Fall" colored markers onto the folder.
