How on earth do you cut very neat, tidy and precise tab slits into your paper/card creations? No matter what method I try I end up with something that looks scruffy. I'm trying to make a slit (through card) that's about 10 mm long and 2 mm wide to close a sculptural book with ribbon.
I often use round holes instead, but I think I should learn how to do proper slits.
I seem to remember just rubbing slightly damp coffee grounds onto the photos with my fingers. I'm sure a sponge would be cleaner and more precise! Coffee & tea wouldn't be acid-free though, I don't think.
