2/22/13 - I added some Angelina fiber to the stream to enliven it a bit, and using Inktense color pencils, added a bit of green to the shrubbery, and some darker brown in the foreground.
I used some upholstery fabric for most of the background, the part at the bottom and center using the front side and the top and just below the stream using the reverse side. The shrubbery is some home dec fabric, again using both front and back. The stream itself is a heavy patterned fabric, overlaid with Angelina fiber held down with the addition of some white beads. I used the fringed selvedge edge of the background fabric on the edges of the stream. Just a bit of silvery fabric and some lace became the rocks on the near edge of the stream. The tangles of thread from the fabrics was too good to throw away, so they added some more texture in the foreground.
I also added a bit of foil to create some frozen grasses here and there, but they don't actually show up that well.
I know this really needs something more -- suggestions and comments will be appreciated!
