I haven’t used them in years, and am ready to part with them.
I usually put free stuff out on the sidewalk, but not sure if it’s wise to do that with these, since they are glass/fragile, and I’d prefer if children don’t grab them.
Also, they aren’t filthy but I don’t really want to bother with cleaning every speck of resin out of them. I can throw them in the waste bin, but open to alternative ideas if there are any.

make a lamp or a nice vase
That’s a creative thought that I have never considered, but am leaning towards rehoming them as I don’t need a lamp or vase. thanks for your suggestion nonetheless.
