Nest the seams and place one side of the pin on one side of the seam and the other side of the pin on the other side of the seam. You only have to pin once and no more slippage. These are one of my "can't do without" notions.
The day I discovered fork pins was a very good day for me! I swear by them! Like Deb said, nest the seams together and one fork pin will pin each side of the seam, keeping them from moving.
