these are the ones i'm keeping in my room

i took out the smaller ones and arranged them in colours to see how many i had

like so

and in conclusion, I think the bookshelf I design will probably have three sizes of shelf: short small at the top, a few shelves of middling-height (like those rainbow-ordered books)

and then a few bigger shelves at the bottom for giant books

i should've counted how many i had, and the exact heights of them all together, but i forgot to do all that

no wonder i felt like i hadn't achieved anything
