For those who wonder about the attraction of my absurdly expensive Jobo sheet film clips, here's a picture. They make it possible to hang lots of film of any sheet format in little space, because the film hangs perpendicular to the drying line, they have pinprick contact area, and because the needle pierces the film, they can hold any format securely. On occasions where I've had a lot of film to process (these sheets are 2.25x3.25, but my largest are 11x14" and 7x17"), they've been worth the expense. I've got 40 of these clips (some purchased new when they weren't quite so expensive, some purchased second hand), and even when I am using all of them, I have room to hang more film with clothespins.
