Sticky Tiki wall decals
New Zealand based company Sticky Tiki produces the most amazing wall decals. Quirky, fun and educational, my favourite is Alphabetica, a deliciously alternative alphabet, home to such wonders as F is for Foxy Fox with Freesias, G is for Green Giraffe, in a Grey and Gold frame with Gerberas and Y is for Yak on a Yacht with Yellow Sails. The small version is about £45 and the large is about £140, plus postage to the UK is about £6.
All stickers are fabric, washable and resuable, so no worries about sticky fingers spoiling the effect. I also love the Hundreds and Thousands design, above, about £35, which you can use to create different patterns.
