Display bits of fabric that you like instead of keeping it in a box. Fabric is art in itself. You can find embroidery hoops all the time at garage sales and thrift shops! Maybe even paint the hoops to give a little color to the fabric hoop wall!
DIY teacup candles: Love these! So cute as a centerpiece on a tea party table or shower table. Perfect given as party favors too. Use mis-matched cups from a thrift store for a pretty, inexpensive shabby chic theme or gift.
Selfie Station Forgo the guest signings altogether and opt for a visual guest book. Leave a polaroid camera at the table so your guests can take a selfie as proof of their attendance and have them pin it up for a fun décor display.
