We have plaster walls so can't use push pins and DH gets chest pains if I put nails in the wall. I hung my curtain rod with Command Performance Adhesive strips; you're supposed to be able to remove them without damaging paint or paper on the wall. I just folded over the top of a large flannel bed sheet and pinned it to slip the rod through. It's been up for over 2 yrs and the adhesive thingys are still holding it (and DH is very happy there are no more nails in the wall).
