Filling borer holes

[Paul Swinhoe]

I want to make a chopping board out of lond dead trees lying on my property. The wood has borer holes that I would like to fill with a clear filler for an interesting look. The filler has to be non-toxic. What should I use?

I have shaped wooded pegs and glued them into the holes, this was to hide them but you could use contrast coloured wood

Thinned, slow drying epoxy applyed with a syringe would be the go I think.
