Hey, those aren't odd sizes, a lot of my work is done with pieces cut to about those sizes. I use pieces smaller than those too.
For me, the odd sizes are usually oddly shaped too. But the generally do get used. When I made my tool stand, then cut it shorter, I used odd pieces where two pieces of plywood butted together. Inside of it, some where used as glue blocks. And, on the outside, just glued on some of the 'artsy' pieces for decoration. Kinda looks like art deco, in a strange sort of way. But it works like a champ.

Some days, the supply of available curse words is insufficient to meet my demands.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
