A member of my design team let me know that your dilemma had been posted, and I thought I would address it directly to avoid any confusion! First of all, let me apologize for your issue! Hopefully I can help! If this were happening to me, these are the steps I would take...
-Check the surface you have your cardstock on. I know this sounds so silly, but even the slightest divot in you table top can cause the result you are describing.
-Try adhering the stamp to the other side of your block. It wouldn't hurt to try and see if it is a little more "level".
-Wash your stamp under hot water and "massage" it. Dab dry with something that won't leave lint behind ( I actually prefer to let mine air dry).
-If the above three "trouble-shooting" methods don't work, send a quick email over to Julie through our customer service address. We will be more than happy to replace the single image for you!
I hope that you enjoy your set! Here's to beautiful butterfly creations in your future!
