I'm so happy to have connected with Eliana. Her communication and follow up throughout this process was great. She created a beautiful rainbow arch for our tent at an outdoor event - and of course if was absolutely pouring that day. That didn't stop her though! She was out there in the rain setting up and everything came out amazing. I'll definitely be reaching out to her for all future events!
