One site I visited suggested taking a placemat, fold it wrong sides together and sew up the sides. Turn right side out, add a loop at the top and you have a cozy. ... View related article.
Simple enough answer, after you ask yourself a few questions. How wide do you want the runners to be? Are they to be all one fabric or are you planning to use some kind of pieced pattern on them? Do you want them to go completely across the tables, hang over the edge, or not go across the tables completely.
Most fabric stores sell flat fold fabrics inexpensively and they are usually in 56" widths; most are decorator fabrics. Regular decorator fabric also comes in 56" widths.
If you don't have the runners go across the tables completety, you can get three 10" runners per yard of fabric. You just divide 36" by the width of the runner you would like to have to get how many you can get from a one yard cut. The length is a given (about 54" after you put in hems) if you use the decorator fabrics.
Many placemats are only 12" wide so to give you an idea of how that would look, put one on a table and see what you think of that width. Would you like it larger or smaller?
If you want the runners to hang over the edges, you figure 20 tables times the length you want the runner. Then divide that by the number of runners you can get from the fabric width. Let's say you have a 5" overhang on each edge, that would make the length of the runner 70" plus 1 1/2" for the hems or 71 1/2". So 20 x 71.5 = 1430" or approximately 40 yds of fabric. BUT you divide that by the number of runners you can get from the width of the fabric. With decorator fabric that would be 56". At 13 1/2" (12" finished width of the runner plus 1 1/2" for hems) per runner; that would give you enough fabric to do four runners. Now divide the 40 yds of fabric by 4 and you will need 10 yds of fabric.
I used a small soda bottle while on vacation. The bottom can be cut completely off using a scissors or you can leave about an inch as a hinge to hold the bottom on the bottle. I wanted to keep the water from evaporating so I left the 'hinge'. Everything worked fine; first time my son didn't kill my plants.
Remove the cap from the bottle, make a small hole in the plant material of your pot. Insert the bottle neck into the hole. Fill the bottle with water and gravity and absorption take care of the rest. ... View related article.
