“I used similar but much larger decals in the military for nose art and tail art.
This is exactly what I was looking for.
Not all is lost if you have a letter slide out of place when you're applying the decal. If it's a small letter just dip your finger in some warm water and apply a few drops to the letter. Gently try to slide the letter. If it still sticks add just a little more water. Eventually you will be able to move the letter into position right where you want it to be. Be very careful not to disturb the adjacent letters while doing this his. Take you time!!!! Gently touch the edges of the letter with the point of a tissue to soak up the excess water then let it dry.”
