In another light-bulb moment, I made a bunch of trinket boxes which worked so well and took up less space. Each box is made of two strips of cardstock and/or transparency. I made most of them 2" by 2" by 0.5" but the following instructions are so easy to adapt the measurements to other sizes.
A strip of cardstock, two inches wide and a strip of transparency, just a tad narrower than two inches.
Score at 0.5", 2", 0.5", 2", 0.5".
Glue the narrow sections together to form a sleeve.
Slide the transparent sleeve into the cardstock sleeve.
2"x2"x1", 3"x3"x0.5", totally customisable!
Sleeves in colours to match the ribbons.
