Hi Rick

I use coffee grounds occasionally, like in a case of a knot that is
darker than the surrounding wood , or with some bark inclusion that has
gaps, the color of the coffee ground chunks and bark are very similar
usually, doing that with paint or coloring dye is very hard, and saw
dust is not the same very often, though I do use that also if I can.

I use coffee ground that has been used, I dry it in the microwave oven,
the reason for using used coffee is that coffee has an oil in it and
when used most of that is gone ( OK and I'm a Dutchman ).

I have tried epoxy mixed, but don't like the outcome, (the color and
texture), so now I use the coffee ground with CA glue only, I pack the
coffee ground tightly by pressing it in the cavity and then slowly flood
the CA glue in, I use thin CA mostly, if the hole is big than I will get
a chunk of wood that almost fills the hole and then fill the remaining
gaps with the coffee ground and then use the CA.

I also use the CA glue with brass or copper filings or dust, the color
is a lot more real than when mixed with epoxy, for the simple reason
that the filled hole is all metal with only the openings between the
metal parts being glue, plus I don't have to wait till tomorrow for the
glue to cure.

Have fun and take care
