Plywood (castro valley)

Wanted: Plywood for attic flooring & patch panel

Hello!
For a project to distract from my unemployment/job hunting woes, I started cleaning up and making the “attic” crawlspace usable for storage, along with having a place to mount the patch panel for our network and CATV drops. Unfortunately I have ran out of plywood pieces to make this all work.

In case you have a couple of plywood, say 4x4, 4x6, 8x8, or some such it would be put to good use.

TIA!
