@Quincy Super-easy refresher is new throw cushions or cushion covers on a sofa, armchair, or bed.
But there have been many times when I've seen pretty basic listings and thought they could be a lot fresher and more inviting with vintage travel posters that speak to the region. For my next project I might use posters like these, but there are so many to pick from I'll have to wait and see what's perfect for the space:
I would frame them and either group them, or put them in tight spaces like powder rooms and front halls.
Just search for vintage travel posters on the web with the name of the town or place you'd like to highlight and you'll see a ton of choices.
(And just so you know how photogenic Quoddy Head Light is in real life, here's a shot I took in October:)
(PS: Can you straighten this and then remove the PS? Every time I post a photo I took with my camera as opposed to my phone, it appears sideways.)
