Looks as though you may be dying two pieces at once, one on top of the grating and one in the bottom of the tray. Is that correct? Great way to get at twofer! Do you have a tute on your ice / painting methods?
Yes there is more fabric under the grate to get every last drop! A friend of mine brought the technique up from her Florida guild for us to try. The painting is an off shoot of a Mickey Lawler class. I didn't want the paint sitting on top of the fabric so I decided to do it like a batik all the way through the fabric to the other side. I use a sprayer and put in the pebeo setacolor paints, tsukineko ink and water to get the color I want and spray away! I also use paints and inks on the fabric before and after spraying. To make the skies I use freezer paper edged with presist to hold it down when sprayed. This is how I now do "tea dying" and over dying to get the same tone on fabrics ie. grays.Tons of fun and variations.
