Good Morning Chiccottage --and thank you for your greeting! So far, I have used my past experiences as an avid antiques/uniques shopper (with an average budget) to dictate the item selection for my booth. I am basically eclectic with a bent toward Country French items. I group items by their genre (Cottage, French, funky,etc) and try to create a mood.
As a shopper, I always walk into an antique mall and go straight to my favorite vendor. Typically, my favorite booths seem to be staged well, reflect a lot of personal style, and have lots of eye-candy. I can spend an hour in one booth!
Florals, pictures, mirrors, and...believe it or not...pillows have been my big sellers to far. My both contains smaller pieces as I am still working my way to buying larger ones. I am now on the lookout for cheap pillows to re-cover.
I have two vintage maple Adirondack chairs in my garage that I am currently repainting and reupholstering. They are in mint condition and I bought them at a yard sale for five dollars each. They will be cottage. I am using consignment bedding to upholster them. (I can find beautiful bedding at a fraction of the cost of fabric of the same dimensions)at my favorite local consignment store. Many of my florals come from there, too.
One particular vendor makes great money with cottage/Victorian decor.
She buys smaller pieces, adds salvage, and shabby's them. Her colors are always off-white, soft greens, and pinks. She has a knack, the experience, and resources to buy small furniture pieces cheap and dress them up. Such pieces have become her bread and butter. She also has a gift for display.
The biggest "repeat-customer draw" for our mall has been the vendor with the primitives. He sells signs, stars (huge seller), candles, lights, and all types of smaller primitive items. He also has some larger pieces. My booth is close to his and I am glad.
The advice I have received is to try to have a few dazzling larger pieces to pay the bulk of your rent while using smaller to ensure sales.
Oh, and one piece of advice that I love...if you find a deal on something you really love...keep it. You may never find that item at that price again. This has already happened to me. For over a year I have been scouting a swag mini-chandelier with prisms. Found one at a neighborhood yard sale for (gulp) ten dollars! I am still drawn to selling it...simply because I KNOW I can make a great profit from it. Time will tell.
Best wishes to you. I like your fall/holiday craft preparations. I am already buying for fall and Christmas!
