I planned my future daugther in law bridal shower in one week. The decorated table was very easy to make.
All it took was a folding table, roll of tulle, inexpensive beige fabric and a glue gun.
I first measured the top of the table for the width, then I added an extra yard for gathers. Measure how long you want it to be then sew by hand. Its does not have to look perfect. It'll look like a skirt. Put the skirt aside.
Take a piece of fabric place on top of table, it's going to look like a short table cloth. Take any heavy duty tape and run it around the to hold the short table cloth you made.Take the skirt and glue it to the table edge, or you can just tape it .
Last cover the edge with ribbon or a piece of fabric.
