Finally! I painted that white plywood this wonderful red-purple color: Dark Iris. The color (on my screen anyway) is pretty accurate. Next I taped it, with the idea of adding stripes.
The blue tape will come off, revealing the original Dark Iris color, with stripes of a lighter color in between. I painted the edges of the blue tape with the background color. It makes a seal, so that blobs of the next color won't ooze under the tape. Well, that's the theory, anyway.
This is the room where I paint stuff. Fabric, furniture, floor cloths. To the right of the newly painted plywood is the utility sink, and under the work surface in the foreground are two small dressers and a rolling set of drawers. In another space I have a raised work table, and there are shelves along one wall. There are also a freezer, miscellaneous chairs and most of our holiday decorations.
