In case you can't read the text at this size, Leia is proclaiming, "I love embroidery." Han, accepting the numerous trips to the galaxy's finest needlework stores he'll have to make in the Falcon, reluctantly replies, "I know."
Above you can see what the case looks like open. On the right it's holding a loom with a pretty awesome death star stitching, and on the left side I believe there's a pocket to hold floss skeins and needles. Geeky Sweetheart initially made this for a Star Wars swap, but liked it so much that she created a second one for herself, and was kind enough to post a full tutorial, including video, so that you too can create your own Star Wars embroidery case.
