Hi there, what kind of decor are you looking to make? I always first hit my local thrift stores looking for deals and ideas. I love the idea of putting real furniture on a porch.
What type of things are you thinking of making?
Could you add a photo of your porch? Wreath is my go to for porch decor. Add plants in pretty planters. Perhaps an outdoor rug. I love spinners and have a few hanging from over head. Rocking chair, cushions for a splash of color.
How about a big porch sign? https://www.homeroad.net/2018/09/how-to-make-custom-porch-sign.html
It’s always effective if you stick to the archetectural style of the home mixed with a touch of your interior style of decorating. Have fun.
