Then, I moved up to a 17 litre Really Useful Box. The light grids are held together using carriage bolts, washers and lock nuts.
The bottom corners were a bit of a challenge as they curve in slightly. We cut out the corner pieces to make it fit.
Then I put the markers in.
I wanted the box to be a bit more decorative, so I added patterned paper to the sides and top.
Please see part 2 of the post for the final project!!
