Back to school Vinyl wall decal with a positive quote for classroom decor: "One Rule Classroom: If what you are doing INTERFERES with learning, HURTS someone's heart or PREVENTS you from being your best self... You shouldn't be doing it! ". GREAT decal for a classroom door, classroom or hallway, school office wall, group time area, whiteboard display, school library, reading room and more. Dimensions: 4.5Hx18W 7Hx30W 8.5Hx36W 11.5Hx48W Each decal is made of high quality, self-adhesive, matte-finish vinyl that gives a crisply painted look to whatever surface you choose to apply it to: walls, doors, windows, mirrors, wood, plexiglass, etc. Clean, dry, and flat surfaces work the best for our vinyl wall decals but they can be applied to textured walls and surfaces. The decal will simply reflect the texture of the surface and may take a little more time and love to make it stay put. Vinyl is removable, but not reusable. Every decal is made to order, so they can be made smaller or larger, if you would like your decal in a different size, please contact us and we can create a custom size for you.
