Neatly applying woodworker's glue to plugs can be tricky. Usually, you just can't dribble a small stream out of the bottle. Instead, pour some glue onto a plastic jar lid or other suitable palette. Then, roll the bottom edge of the plug in the puddle of glue to apply an even coating right where you need it. Glue buttons, Shaker pegs, axle pegs, and other similar parts the same way.
