Sorry for the potato pic, but here's the first prototype. I'm not too happy with the lattice bars, both in their appearance and how much work stripping the plywood backing takes, but there's no way my saw can cut pieces any thinner. I'll try and figure something else out.
I have some shoji paper on the way, I haven't stained it, and the sanding job on the kick board isn't great, but I'm fairly happy with it. For the twenty bucks everything cost, it's much better than the Cobaanii kits at least. I also made a base board that will fit 8 of those Pinktank tatami mats and fits right in a Detolf to attach these to.
