Super Newbie Idiot needs and L shape
I haean'tbeen on PS for a while and was never really that good at it. I am having to go back in it to get a concept drawing to show someone. I need an L shape to male a sidewalk. I looked at shapes and don't see anything in ploygons. I just want to draw the "L" and and be able to resize it horizontally and vertically. Then I want to be able to put shapes on the layer. Can you help a newbie/oldbie?
Here is what I trie to draw that took an hour.
