I really liked the demo and the collage stamp the lady used. I don't have many, but it worked pretty well with this stamp. I will be looking for more collage stamps that will work with this technique!
What you have created is really a work of art. I went back and read the directions and I hope to be able to do this, but I don't think I have a collage stamp, but perhaps can create one, by using several acrylic stamps together on a clear stamping block. Yours is so beautiful.
