Clean paint lines on walls and trim
I'm in the process of repainting our walls and trim and I don't seem to be able to keep from getting either wall paint on the trim (crown and baseboards), or trim paint on the walls. I mask off the trim and walls with Frog tape, and I'm not getting bleed through, but since the walls/ceiling/floors are uneven, it seems impossible to get the tape itself in a clean perfectly straight line so that the paint edges are clean. I just repainted the walls a much lighter color and taped off the crown and baseboards. When I peeled off the tape, there are several spots where the tape edge extended just a hair onto the wall and a sliver of the old darker wall color is showing. I had the same problem with the skinny top edge of the baseboard.
How do you tape so that you don't have these problems? I don't have a steady enough hand to cut in without taping.
