You are the undisputed "Rembrandt" of Pennant restoration.
I'm seeing stains in tones of grey, brown, red and blue all on this pennant, so it will be an excellent test of the bleaching process. Since it's a whopping $55 investment, I'm gonna fight this one solo (no seamstress).
Many thanks, and I'll stop posting now, as I'm sure we've bored most people to death with this bleach banter. Next post will be the "before and after" results.
