DB has worked really hard on his box and at last it is finished.
We had an old rust coloured tablecloth so used it to line the inside. Originally, he used double sided tape but it didn't stay put in places. Then bostik was used and that made it a bit messy. In the end, he used small fine tacks. That certainly made the fabric covered card stay put. Unfortunately, hammering them in, made some of the leg joints where they joined the box, spring apart.
Out it went again into the garage to be glued together. Eventually, with the addition of a nice brass handle, it was finished. Here is the before and after internal pictures.
