Something else you may want to consider is one of those adjustable angle brush holders. Used by itself, it provides about 8 inches of extension, great for cutting in walls at the ceiling. Just set the angle to whatever is comfortable for you, lock it and you're on your way.

The REALLY come in handy for brushing fascia boards from the ground. The handle is threaded and fits on any painter's extension pole. For angled-out fascia, just set the brush holder again to a comfortable angle and paint away. Beat's the heck out of moving a ladder around your house at 3-foot intervals. (Oops, don't try it on a 2-story house unless you keep your paint bucket out in the street somewhere.)

 

Just so everyone knows - the longer the extension on the brush holder the harder it is to control the brush. Ofcourse the more practice [as with anything] the better you'll get. Although not used often it is a valued piece in my array of painting equipment.

 

You may not need it often, but when you need it, you need it
