Collage (from the French: coller, “to glue”;[1] French pronunciation: is a technique of an art production, primarily used in the visual arts, where the artwork is made from an assemblage of different forms, thus creating a new whole.
This art form has such a wonderful ability to to be used in so many ways; Collage, Artist Trading Cards, Art Journaling, Mini Canvas Art, scrapbooking and decoupage to name a few.
I have a few favorite Etsy shops that create some great digital downloads.
- Karoliks. (This shop has a wonderful variety of Digital Collage Sheets and Floral Digital Paper . From bright vibrant colors and flowers to earthy Vintage and textured papers. Tropical Floral and Pa
isley Background are two of my favorites and I use them both quite a bit.
