PowerTape® is a single sided tape that comes on a convenient self wound roll. To use it you simply lay the banner face down on a table, apply PowerTabs® and strip PowerTape® along the top and bottom edge of the unfinished banner on top of the PowerTabs®, punch a hole through the tab center hole, the tape, and banner media. Then, fasten your rope, and you are ready to go. It may seem obvious, but the tape goes on the back of the banner.
There are a few tips that will help. First, it helps if you can clamp both ends of the banner on a table with just a little tension to remove any wrinkles. Next, you don't need to place the PowerTape® exactly along the edge. It is better to give yourself ¼" leeway to allow for any slight wandering as you go down the banner. You will develop your own technique, but we have always found it helpful to pull off an arms length of tape at a time and lay that down, using some tension to keep the tape straight then pull off another, etc.
