Patience
I work at a Community College and Sasquatch is our mascot.  I ordered three 7' decals.  My feedback is below:<br /><br />1.  When putting up a decal this big you need at least two people.<br />2.  Take your time, follow the instructions, and go slow.<br />3.  Have a good clean smooth wall.  My experience was if the wall is not extra clean the decal will pull off the wall while removing the paper.<br />4.  When pulling off the paper I would go over and over the decal with my rag before pulling the paper to make sure it was smooth.  I worked from the middle out on each section.<br />5.  I did not have good luck removing and reinstalling the decal as it was then stretched out.<br /><br />I tried to do the first one myself and ended up with creases.  I messaged and then talked with the owner and he gave additional tips.  My second one took two people 1.5 hours but it was worth it.  The decal is a beautiful shiny black and there is not a crease or bubble in it.  Photos attached.
