Do you know what a “vignette” is? I love the definition of vignette on vocabulary.com: “A vignette is a brief but powerful scene. A good vignette leaves you wanting more.” As a general rule of thumb, whether indoors or outdoors, decor vignettes look best in odd numbers.
Sometimes the best place to start creating garden vignettes is to look around your own yard and/or garden shed for junk you can repurpose. A great example is this chair hubby made out of sticks and limbs from a maple tree we cut down. I parked a wicker basket of annuals on the seat and twined a Nelly Moser clematis around the back. Mr. or Mrs. Robin liked it too and stopped in for a visit. It looks super cute tucked into this flower garden.
