Wire hung canopies are a great idea! They provide adjustable shade to make the outdoors comfortable under even the hottest sun. And they are beautiful! But a careful search of the web will reveal very little about how they are made. Tapping the "eBook" tab will resolve that problem. Anyone can build custom fit canopies using these instructions. And the "Calculator" tab gives access to the most accurate way to determine the measurements that will result in a perfectly fitting canopy. An accurate and detailed list of all the materials and hardware required for each project is also provided. The "Videos" tab lists the helpful videos that Sailrite has prepared to further guide this work. And, finally, the "Sailrite" tab pulls up the Sailrite Web Site. Here is where research concerning fabric and hardware can be carried out. It is even possible to create a shopping cart or a wish list right within this app!
