I've been working for a very long time trying different techniques, following other people's instructions, learning the best way to do things, and I finally found a process that works for me and incorporates the things I like, and (I think) I do best.
The base for this collage is composed of various papers (old book pages, crinkled paper bags), covered with a bit of modeling paste, then a wash of acrylics. On top of that I placed an inkjet transfer design (using Kimoto Silkjet transparencies and golden soft gel gloss). The design for the transfer came from a scan of another collage I did, and added to in Photoshop.
I'm excited that everything turned out the way I hoped! This piece, and a companion piece, is online at http://www.etsy.com/view_listing.php?listing_id=7830898.
