Barb, I pack such voids with sawdust first and then dribble in thin CA. Putting the glue in first, and then attempting to rub sawdust in has generally left me with my blue nitrile glove glued to the wood and sawdust glued to my shirt or jeans.

I will also use Gorks Goodfilla if I don’t have sawdust handy. They have a variety of colors, but I generally buy the neutral in a bag (the powder lasts forever as long as you don’t get it wet) and then mix dyes to get a match, but sawdust and CA will be a good match (a little darker than the wood, usually) with less fussing around.

May you have the day you deserve!
