You can decorate your tea party very simply with flowers. May is peak peony season. Place fully opened peonies in small tea cups or plain white mugs and set them around the table for easy and beautiful decorations.
Tea parties have an inherently vintage feel, so play that up by going to your local thrift store and finding some vintage fabric (look at sheets and pillow cases too) and use them as table cloths.
Topiaries are so easy to make and add height and drama to your tea table. Make a ribbon topiary like the one pictured above on the ParTea Planner’s blog. Using a wooden dowel, a foam ball, floral foam, ceramic pot, lots of ribbon that you’ve cut into 4.5″ lengths and some push pins. Cut the floral foam to fit inside the pot. Secure the wooden dowel to the ceramic pot using floral foam. Make the ribbon into loops and secure to the foam ball using the pins. Place the foam ball on the other end of the dowel and voila! Get creative; use silk flowers, and tulle to cover the base. Paint your wooden dowel and ceramic pots, for added color.
If you have a fabulous umbrella or a white lacey parasol, hang it upside down over your table for a lovely focal point. Tie ribbon to the parasol and let it hang down as lovely streamers.
