I want to make some light duty corner shelves and was thinking it would be really easy to mount them to the wall with pocket screws. Unfortunately, the studs aren't in the correct place, so I'll be going into sheetrock. I usually use Pop Toggle anchors in sheetrock because they hold well, but the screws must be perpendicular to the wall. Are there any good sheetrock anchors that would work well with the screw going in at a slight angle?
