I print labels for some products that I ship and when I try to apply the label to the curved surface of the jar the label stretches with the slightest pulling and causes wrinkles. So it does not totally flat but has wrinkles at the edges where I was holding it with my thumbs. I did not have this problem before with your product so I can only believe that you made the labels thinner than before.
The Avery Word Template worked for my text label. The labels fed and printed well in my HP Inkjet. The label stuck solidly and did not smudge when smoothed onto a fiberboard carton. I will buy more when needed.
