New favorite combo with chalkboard paint: CHALK INK MARKERS! Who knew?
Once I painted the wood rectangles (bought them at Michaels and they have lots of different shapes and sizes), I sprayed them with sealant to weatherproof them. My sister was watering the flowers and "did not know" that I was on the ground below her and sprayed me and my cute little garden markers. Thank goodness the water beaded right up!
Michael's also sells garden stakes. You can either nail them together or glue them together, but I recommend spraying your Sealer after you have attached the stakes so that water will not cause these to rot over time.
