I did take a pic but I'm sure you guys will know what I mean. I have an extra tape measure pulled out and taped the length of my cutting table. I just put the box of film on the end and pull out the film amount that I need. The tape measure is under the glass and wont get in the way or get hurt.
Very convenient for pulling back glass or roll-ups, anything really...just look down and theres the length. No more holding the film with one hand and trying to find a tape measure and then all that. I'm sure you guys may have some clever ways of doing this yourself but this may give a few a new idea.
