I hung my wet negatives in various places after developing, usually with clothespins. But when I had two or more, I ran into free space issues. With either a single clothespin or this device, it is important to hang the drying negatives in an open area. I used a plant hook in the ceiling most of the time. This allows me to utilize the open space in a closet or other clothes rail or ceiling hook (I use a ceiling hook). It also allows me to hang more negatives than I will ever handle at once without running out of hanging space. Overall a great product.
