Bubinga Rimmed Clutch Box BatchLee Krasnow2020202110I learned a lot from making the previous two copies, and so put that wisdom to good use along the way of making these ten.
2020 Clutch Box BatchLee Krasnow202020202I did not do any kind of spiral inlay on the lid for these two, in a precursor to what would become the "standard edition"
Removable Lid Clutch BoxesLee Krasnow200420046I made the same mistake with the lid inlay pattern during this batch, and so just like the previous 2 copies I needed to flip the lid tiles over and thus the spiral pattern on these turned out mirror image from what I had intended.
Hinged Lid Clutch BoxesLee Krasnow200320031I had originally intended for the lid pattern on #2 and #3 to be the opposite direction spiral but my production technique at the time resulted in chips during the cutting process which necessitated me to flip them all upside down in order for it to look nice.

Typically when I mill down rosewoods, I get rid of the wonky chunks that have remnants of the sapwood or any wormy bits, yet in this particular case the plank I was working with had enough of said material to allow me to make just one copy like this and so I thought it would be fun to showcase something that would otherwise just go to waste. The client was pleased insofar that the wormy puzzle matches the wormy rafters in their castle, so it was a win/win situation right off the bat.
