We print our own patterns to install our channel letters. I have been using a roll of old grid paper that has been great, my installers really like it because it has some weight to it. Unfortunately that roll is out and I can not seem to find online anywhere the material based on the tag that's inside the tube. I would like something comparable, possibly even slightly heavier. Does anyone have any suggestions of where I may find this material or what are other people using. It needs to be heavy enough that when my installers are out it doesn't rip when they are using the pattern. I have included a photo of the tag on the tube. Any suggestions would be helpful!
