   Years ago when pine was poplar, especially knotty pine I would mix a couple of different colored "Plastic Wood" together to get the color of the knot and fill the voids and sand when hardened. Sometimes it was difficult to see the filled area as it matched the knot so well.

   You over fill and I usually use enough so that when it dries and shrinks the void is still filled. If it is a deep spot you might have to fill it a couple of times to allow for shrinkage.

   Epoxy can work well.  You can also add pigment or an appropriate dye to the epoxy to give it some tint.  It's good to be aware that color matching a filler, epoxy or other, is best done after a coat of your chosen top coat has given a better idea of the final shade.

   One approach is to use polyester casting resin, available at art suppliers. It's the clear as glass product that you sometimes see bugs displayed in. No disguising the voids, looks like they are filled with liquid glass.

   Beat it to fit / Paint it to match

   I use epoxy, usually tined to match or contrast with the knot.

   i use epoxy with sanding dust I have saved (festool vacuum bag). Use a hard block with sandpaper when leveling out repair because Pine is softer than epoxy.

   Good stuff with minimal shrinkage.  It can also be coloured with dye before or after filling, to make either a perfect colour match or to variegate the filled part of the knot, to look more knot-like.

   I don't know where you'd get it in the US but a Google search might find a retailer.

   Here are a couple of pics of knots in oak filed with "dark oak" shade of Brummer.  They've also had a little painting with even darker oak stain, using a fine paintbrush, to make them appear less "filled".

   Why not a dutchman?

     Take a router and make the hole an interesting shape. Remove the wild grain around the hole to avoid drawing your eye towards it.  Make the dutchman slightly tapered and use care to somewhat match the grain pattern and you can get it to the point of  very nearly invisable..

    That or celebrate the knot with a contrasting wood.
