Recently I was in Fort Bragg, California and happened upon the cutest little flower shop in an old lumber building that had been renovated into a bit of a mini-shopping mall. I thought the owner, Jennifer, had done a very cute job of decorating her shop:
I thought for sure she had hired an artist to paint her walls and was so surprised to hear it was actually stickers! Check out this company: StickerBrands
They have a section called Floral Designs which is full of great ideas.
For more information on the shop I visited:
