Guitar Guts

I am working on a pair of slippers for my mother. I make sock-shaped slippers with two strands of worsted weight acrylic and #8 dpns. Mom's feet are smaller than mine, so I'm almost done with the second slipper. I'm ready to begin decreases for the toe, and then I can start on slippers for my dad.
My parents are snow birds, wintering in Texas and on the road for most of the summer. They feel a bit of a chill when they come north in the spring, and they say my slippers are well used and appreciated all year long. I'm making them each a second pair to keep in the RV.
Mom's slippers are red, and the picture didn't turn out well, so I decided to post pictures of J's latest acoustic guitar. He finally got a rosette that was good enough, and is now working on bracing the inside. He asked me to take some pictures to document what he did, so here they are. I thought Diametrag might like to see his progress.
