For those that do this already, nothing really new here just my process , but this was a fun little project as I was trying to recover from a recent bout of flu (despite my flu shot.) Using some Castin Craft Clear polyester resin, I mixed up a batch of colors and cast some pen blanks. Uses 3/4in PVC as molds. Youtube video attached, thanks for watching!
