lastfuse 4 Posted March 21, 2011 I've only done 1 lighted sign before and I just reused the old plexi. I'm looking in my substrate book and there's TONs of options. The sign is 87" by 107". What are my best options and where do you order your material? All of my local suppliers recently moved out of state. Thanks for your help! Share this post Link to post Share on other sites
