I have hundreds of small watercolor swatches. I kept them in some smaller boxes, but their size (110x164x48 mm) was not optimal for the Billy bookcase’s depth (I need 260mm depth instead of 164 mm).
So I made 6 new boxes (trays) + enclosing containers to fill the available space. Since the trays are pretty long, I split them into two with a divider wall.
- 2.5mm bookbinding board
- Efalin (black) for the cover outside
- Napura Khepera (black) bookbinding paper for the lining
- PVA for box making, Planatol Elasta N (paste) + Planatol BB (glue) mix for lining
