✕DO NOT FORCE THE FIT
- Cutting a line — no corner, no crisp edge; use an angled brush (oval-angled 80734, or a flat sash 80803/80752).
- Control-scale and narrow work — three inches of loaded oval is a lot of brush; for smaller faces and better control the 2-1/2" 80737 is the more manageable straight oval, and small trim needs a sash.
- Oil finishes if the fiber isn't natural — verify before varnish or enamel.
- Detail lay-off in tight spots — the width that makes it fast on open fields makes it clumsy anywhere confined.
