Now the white 18" silk is a simple prop. Normally you would use this with other magic tricks. Such as appearing candles, flowers, balls, ect. But even though this is great for revealing and vanishing items, this could also be a trick in itself.
An example would be if you, the magician, tied a knot in your white 18" silk (that you bought from MJM Magic -wink-) then after you let the audience examine the knot, you begin to pull the knot off of the silk! (Sure that you need to learn this on your own because the silk doesn't come with any instruction booklet, but here is where your imagination comes in)
White silk (like any silk) is used in numerous ways in effects. But a normal magician's outfit would be black and WHITE. Now that you bought a WHITE silk (from MJM Magic), you can use the silk in combonation with the clothing to make some interesting variations in appearing the silk. How would this be done? All you need to know is that the white silk will blend in with your white clothing (helping in hiding it as it blends). So then- (I'll leave the rest for you to figure out :D )
Anyway, to make a long comment short. An 18" silk is best used in hiding and revealing props while a white silk is best in helping to blend in with the prop you are trying to present or the clothing you are wearing. So mix them together and you get an 18" White Silk (by MJM Magic XD )
So cheers! Good luck, have fun, and BUY THIS!
