We're painting our interior walls and trying freehand cutting-in for the first time (i.e. no blue tape). It helps that the wall color and trim color are not highly contrasted, and we're starting to get a feel for it.
cutting in with the freehand method
Of course, as with most things, there are gray areas. Some products are out there that allow you to cut in with a flat sponge tool (as in the image below). We're using a plain old 2" sash brush and it's really working fine. We're enjoying the fact that we aren't plunking down $15 a roll on blue tape or spending a lot of extra time putting it up. It does add some need for extra carefulness when you're doing the actual deed but - at least for our low-contrast cutting in - the freehand method seems to be working just fine.
