I started gluing a bunch of cutoffs together to make endgrain coasters, but the weather (my shop is outside on my balcony), my lack of skill, and not having all the tools I wanted made it difficult, so I set the project aside. Maybe I'll get back to it when the weather warms again.
Also, depending on the size of the cutoffs, you can easily do keychains. I know lots of vendors sells the kits, and you can trim the tube to fit your blank size. Great for little gifts or a cheap alternative to a pen if you're selling. You can sell them for $10 or $15 and still make a nice profit margin because the blank is "free" and the kits are only a couple bucks (at least last time I looked).
