Sorry for the absence. Hoping you'll forgive me as I had my second child 4 months ago. This is a short one as I'm in a bit of a hurry but thought I'd share this as I go...
Process: 1. Divide your walls into squares the size of a width of wallpaper (beware not all wallpapers are the same width as I learnt the hard way!) I put a boarder in for the alphabet as it didn't quite go. 2. Paint the squares you want painted with paint samples. 3. Cut the wallpaper samples you gather from DIY stores and wallpaper paste them in place.
