beautiful but hard to peel off

These stickers turned out BEAUTIFUL! I purchased them for my grooming shop, and for when my dog does visits as a therapy dog. Unfortunately, I am having a heck of a time peeling them off their backing. I just want to peel them off, and give them to a child or customer - I can't spend 2-3 minutes each time trying to find an edge so I can peel them! I ordered the sample pack of stickers, and other stickers - such as the glitter and holographic ones - were so much EASIER to peel. I will buy those instead next time.
