Technically, these are the second set I've done like this. I forgot to take pictures of the first set due to a time crunch.

To make these, I fill my blank insert molds about halfway with clear resin. I then fill them as much as possible with cherry wood curls/shavings. I let them sit a few minutes before topping off with more resin and try to cram some more wood into the mold.

I had attempted this with redwood shavings, but lighter woods are almost transparent once the resin goes into the pressure pot.
