Jeff:
Yeah I think I see it. The series of squarish openings on each side just above the seat frame. For stuffing fabric into. OK.
I'm working on an oxbow chest with claw feet, which is near done, but I've been avoiding it lately because it's been a real sphere comminuter. I work in total isolation and have had no instruction. Since deciding to do it all by hand (almost), I've really increased my challenges, since I don't know how. Plus, the proper construction/assembly sequence is not at all obvious to the ignorant. I still haven't decided how I'd build a next one.
Personally, I love the pics. Keep 'em comin'. Do you have to compress the files?
