If you have a need for a swag lamp and want to be a little creative, you can easily make a string lampshade swag lamp very easily.
First you need some thick string. Not as thick as yarn, but thicker than kite string. Make sense? Actually any thickness will do, but you will like the outcome better if your string is about in between yarn and kite string. Some people have said that crochet thread is just about right for this.
You also need some fabric stiffener. You can pick this up at a local craft store. Mix up a solution in an old jar or other usable container. This is very important as this is the stuff that keeps your shade together.
Next, blow up a party balloon the size of the lamp you want. This can vary as much as you like. This will determine how big your shade is.
After you have blown up the balloon , tie it off and wrap the thread around the balloon. A trick is to soak the thread in the fabric stiffener first. Just be sure that the entire string is coated as you wrap around the balloon.
Now hang the balloon to dry. It may take overnight to dry good, but make certain it is dry before you pop the balloon. When you are sure, pop the balloon and cut a hole at the top , just big enough to get a light bulb through.
Once you pull the balloon pieces out, you just need a bulb kit from the local hardware store. The electric cord should have a on/off switch built in. Put the bulb end inside your new swag lamp and affix it to the shade with a small wire.
Caution: Depending on the wattage of the bulb this could be a fire hazard, so either use low wattage bulbs or maybe a CFL bulb that does not get hot.
