If your venue has a drop ceiling then you can very easily hang lights! Simply use some string or zip ties to secure the wire to the metal frame. The image below shows how you can simply loop around the frame of a metal drop ceiling.
If the walls of the venue are drywall or fairly smooth you can use the Command adhesive hooks available at any local department store. They can easily hold a light string so long as you use a couple hooks to disperse the weight.If you'd like to browse all the lights we recommend for weddings, click here!
