I've used all kinds of papers: pages torn from books (especially foreign language ones), sewing pattern paper, brown paper bags, leftover scrapbook paper, etc. The trees are stamps I carved.
I'm also going to try something new by offering these for sale. Someday I hope to have my own art web page, or an Etsy shop or just a blog with artwork for sale. But for now, I will just offer them here. The images are about 6" x 8" and they are sewn onto 9" x 12" Bristol paper. If you are interested in buying one, you can email me or leave a comment. I have a Paypal account and would also be willing to do a trade.
(plus $5 for shipping and handling)
The quote throughout the background on this one says: "Come forth into the light of things. Let nature be your teacher." - William Wordsworth
I have a few more I'm working on as well.
