I've built up a pretty good pile of small scraps of wood I just can't bear to toss over the years: verawood, ebony, rosewood, mahogany, purpleheart, but even just some nice maple, sitka spruce, red cedar, walnut, etc. I started carving some into pendants this winter, and some look pretty good, but I'm looking for ideas for really small or weirdly shaped scrap -- everything from 1/2" lathe ends with a hole in them, to long 1/2" x 3/8" x 4', a small clip of the pile under the picture.
I've heard a few people just throw them into baggies and sell/give to crafty folks, which I might do in the end. But I figure if I can make stuff to give away as gifts or sell at a craft fair, all the better... but outside of jewellery, not sure what else to do. The are NOT big enough for endgrain cutting boards, and most have a couple rounded or uneven edges.
As long as they're both water-based and you scuff it up a little with 120 beforehand, you should be fine, although I haven't used that specific set of finishes. Can always do the tried and true and try it out on a test piece first if you're really worried.
But yeah, TBH, even if you went crazy and used epoxy or urushi, pretty sure it'd get scratched up with kids being kids. I use 10+ coats for specific applications, and it's very scratch resistant (in fact it seems more more than the technically harder urushi... this is where I redact a few paragraphs of finish hardness discussion...), but standing up to kids, nah.
