Getting back in the saddle again after not making bows for a couple years, and wondering about some knots. Making this one for my girlfriend and don't want it to blow up on her. Did I leave enough material on these funny knots or should I go down another ring and leave a little extra? Thank you! 
Those are on the back, I assume? The top one I would put a patch over (sinew, rawhide or other material just to prevent a splinter lifting) after digging out any loose wood and filling it with CA glue, as Eric suggests. The other one I would just hit with thin CA and carry on.
I made a scraper out of a concrete nail to carefully work pin knot clusters on the backs of limbs from every direction.
You have the coolest tool selection, Eric.
