Unzip the attached files then double click on GuideWrap.htm.
The zip file contains 2 main things GuideWrap.htm and a 
directory named threads.  The threads directory contains 
files that are the color samples that are used.  You need to 
unzip everything in the zip file.  The threads directory must 
exist in the same directory as GuideWrap.htm and it must 
contain the color samples. Then, when you select a color 
from the drop box it will automatically change. To change a 
width type a new value then press enter or click some where 
else on the page.
