Not having had any experience in packaging design, I’m not surprised I just found a mistake in my drawing. The problem is just that I no longer have the time to correct my drawing, redo the printing, and remake the packages. I’ll have to make do with what I have.
I would have caught this if I could spend just a little more time testing my design. I might have needed just an hour or two. It is so unfortunate that OCAD is on “summer hours” and we no longer have access to any proper facilities on weekends.
