Hi I am a twister making the leap into Deco! I am planning on taking the CBA test this fall and I have a lot of practice to do! I have a question for you all, I have a client that does not want an arch so I want to do an outdoor balloon wall in between two mason pillars. I'm thinking of writing 20 years in balloons in the wall using the duplet square pack technique, and hanging it using 100pound Dacron line. Will this hold up in a nice rectangle? It will be outdoors!
