I would love to be advised as to how to cover holes in my walls. I have hung and re-hung pictures and the walls look terrible. As you can tell, I am no painter!! I did attempt to do this on my own, but created a much bigger problem. I filled the holes with lightweight spackle. The directions said no sanding required, dried quickly, and was paintable in minutes!!! I filled the holes, painted over them, and my wall looks like it has polka dots all over it!!!!! I used the exact same paint that was already on the walls. I know I have made a very stupid mistake, but again, I know nothing about painting and have had to learn the hard way about hanging and re-hanging pictures!!!! Please, please, please someone with painting knowledge help me with this problem....seems it should be simple but I have created a big mess!!!! And, will I need to repaint the entire walls???
