It's that "most wonderful time of the year" when we're starting to get calls from our customers with regards to hanging Christmas Lights for this holiday season. As a well established lawn care company that's still fairly new to the holiday lighiting industry (this will be our 2nd year at it), we were hoping for some input from those of you out there who have braved the "holiday lighting frontier" already, and ask to draw on your experience. Based on the photos that I've uploaded, does anyone have suggestions (besides drilling), as to how we might be able to affix christmas lighting to the edge of these parapets? Our customer would really like to have the whole lot framed in with lights, and we're trying to get the most effect for the least amount of "damage" (drilling) to the property. Any thoughts? I would very much appreciate it!
