In the image above, part will be in cotton and part will be in noil. In the image below, part of it will be cotton and part in gauze. It is a subtle and interesting look.
This is the gauze with the fusible web on the back. The fusible cuts down on the "airyness" of the gauze but you still have that wonderful texture.
Here's the silk noil with fusible web on the back.
Digital cameras are great for taking pictures of different layouts to compare them side by side. Years ago, we relied on a Polaroid - this is so much better. This is one of the arrangements.
And this one, although I'm not crazy about the long narrow strips in the center.
It still needs something and I thought of silkscreening a tree on the light green area; the branches would fall into the window, which appeals to me. However, silkscreen is permanent and scary to just jump in and do. I found an easy solution. I went to a sewing store and bought some "tablecloth" fabric in clear plastic. It had a lot of body and only $1.98 a yard. I silk screened the image on the clear plastic and laid it over the quilt. You can also screen different color paints to see what works best.
