A note on your paint — Wash & Wear and other low-VOC paints, and walls painted without a separate primer, carry a higher risk of paint chipping. All paint wears with age. The test piece in your order shows you how your wall behaves. It's a guide, not a guarantee.

Beautiful, quality, easy to use

They are beautiful and quality just as pictured. As easy to put on as said. I was relieved that they were worth the expense and easy to put on as we were doing it as a surprise the night before my child's birthday! They absolutely love them. Few intricate bits were a little tricky to manage but got there.

It depends on your paint. Our fabric decals are easiest on fresh, clean, non-chalky paint over a proper primer. Old, flaky or chalky paint can lift when any decal comes off. That's why every order includes a test piece: stick it somewhere out of sight, wait two days, then warm it with a hair dryer and peel slowly. Not for textured walls, raw plaster or chalky surfaces.
No. That's the difference between fabric and vinyl. Our thick matte fabric has no sheen, no white border and no plastic look, so the watercolour art reads as paint. Customers tell us family ask if the walls were hand painted.
No problem. Fabric is more forgiving than vinyl. Lift the piece and move it while you install. If it has been up for a while, warm it with a hair dryer first. Big pieces are easier with two people.
Fabric decals sit flat on the wall, with no raised border for little fingers to catch. Most parents place them higher up, out of reach.
The matte fabric holds the colour of the original watercolour artwork well. Screens vary, so if you're matching a colour scheme, email us a photo of your room and we'll help.
