I’ve used Wall-Dog screw anchors and they hold very well. We have a problem with the window valance side panels that cover up the left and right hand edges of the window blinds. The screw that attaches the bottom of the valance to the wall seems to be susceptible to pulling out. Probably those roads in the Yukon and Alaska
At any rate the Wall-Dogs have held up very well. You can find them at most any hardware store.
