I tried to be clever with some of the pieces, as I felt some of them were a bit "in your face" with the stark white/cream background against the orange rust, so I decided to immerse the fabrics in tea to tea-dye the background. The result wasn't what I expected .... instead a grey/brown fabric.
The tannins in the tea worked against the wonderful orange/gold colours of the rust. Although it changed the visual context completely, it left something quite different and unusual in its own right, even if it wasn't was I had hoped for. Isn't that usually the way?!
Not sure what I'll do with these samples yet, but one of the larger pieces pictured below will be used in my wall hanging.
