Well, the computer technician fixed it. A couple of weeks ago he changed a firewall setting on the router - today he changed it back to it's original setting and now I can post photos again. Hurrah!
This is the pile of fabric pieces and the cache of buttons I ended up with once I cut up 10 of Russ' old uniform shirts. I have been busy since then folding, binding and clamping the pieces ready for the Rust and Tannic dyeing day at a friends house on Tuesday. I'll post a photo of the prepared fabric tomorrow.
