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.
Thank you in advance.
