Having tools scattered around my sewing machine sucks. Let's go.
I drew the layout on paper and cut out two rectangles from cardboard.
When cutting it, I found out that one side always gets shrugged. So when you cut cardboard, do it so that the piece you want to get is at the right from your scissors.
I made it from scraps of the most beautiful fabrics I own. Unfortunately, the green one was too narrow, so I finished the edge with a strap of fabric to stay as big as possible.
I sewed it on the blue piece and made compartments.
The lining was a bit of patchwork as well, as I didn't have big enough scraps.
I sewed the lining together with the upper piece. When inserting the cardboard rectangles, I left a small space for upper fold and big for the bottom. I sewed through the layers around the rectangles to keep them in place.
I made a tunnel and put in a cord to make sort of stopper for the stand.
Finished.
