I mentioned this on Facebook last week, but my husband got me involved with sprucing up his shotgun.
He stripped the old finish and stain off the stock and forend from a secondhand shotgun. The old crosshatch pattern was sanded almost completely off from previous users' refinishing. I carved some new grooves into the stock and forend. Carving a curved object certainly wasn't what I'm used too, and my carving wasn't perfect.
Then he stained the pieces and put it all back together. It looks much nicer now.
Husband & wife collaboration for the win!
