A: The smoother the surface the better. (even glass, metal, furnitures and non porous tiles.) We know that there are many types of textured wall surfaces. Our wall stickers will work on some these textured surfaces with varying degrees of success. We want to make every effort to insure your happiness with our wall decal products, so we offer to send our customers within the US, a small sample of our wall stickers in a letter sized envelope so you can test our wall stickers on your walls. Please note however we don't have samples of each wall sticker set just whatever we have available as extras at the time. Just send us an email and let us know your address.
