I asked some time ago if anyone knew whether Silver Spring Creative Reuse
was still functioning. I just spoke to the founder, who said it was not,
and that she wasn't sure if it would resume.
There is an organization in Alexandria with a similar mission, collecting
still-useful materials for arts and crafts, etc., thus diverting them from
the waste stream, and making them available to teachers, artists, and
others--Upcycle:
https://www.upcyclecrc.org/
And one in Baltimore--Scrap Creative Reuse:
https://baltimore.scrapcreativereuse.org/Material-Donations
Both are accepting donations by appointment right now, and both make it
clear what items they accept and those they don't.
