I came across this ad (storybook theme for a flooring company) that was a pretty exact replica for Rana's cottage interior.
It's got the tudor glass bay window seat, exposed beam ceiling, hand-plastered walls, curved arch-shaped doorways, fireplace with rough-hewn mantle, hardwood floors, etc. I had to buy the magazine to get it in case I couldn't find it again online (I did above). Seeing it gives me more confidence to make my version of it.
Over the weekend I brought out the beautiful fabrics that will be used to make Rana's elaborate clothing. I was surprised to see that the wall colors, already painted, matched exactly--But I mean--exactly. That made me feel so much better.
Today I decided to simply mix a kitchen-sink batch of pomegranate/rose/maroon color to even out the shading and de-emphasize the irregular plaster texture. I feel it worked and I'm perfectly happy to push on now to finish out the interior.
