Do get innovative with wallcovering. Use texture and metallics on the ceiling to create the illusion of higher ceilings and in wall paneling insets for a gallery effect. The use of large prints for wainscoting around the lower section of a room and grass cloth or silk above the wainscot wraps the space up like a jewel box; I love this technique for dining rooms especially.
Do make sure all wallpaper installations include proper preparation; I highly recommend the walls be primed or ‘sized’ as a base coat then add blank stock (thick plain paper) as an underpayment prior to installing the finished goods. This ensures a flawless installation where seams come together and covers many imperfections on the wall that might peer through the end product.
Don’t be afraid to custom color a wallpaper. If you love a print and it’s unavailable in your favorite palette, ask the manufacturer what the minimum material requirement is for custom coloration. The answer is often surprisingly reasonable and many wallcovering resources welcome custom orders.
Don’t use inappropriate materials for areas that need more durability. In other words, don’t use a silk-based wallcovering in wet rooms where water and steam can stain and damage the goods and don’t use a paper product in heavy trafficked areas such as kitchens and bars: Use a coated paper or vinyl base for its washability and strength.
Don’t even think of identically matching wallpaper to fabrics or artwork in a space. Have courage and mix and match. Use texture with bold pattern and be ready to see your creative awesomeness come to life!
