As everyone in here knows, any material should be covered by paper tape. So, I bought a 12" transfer tape but the quality was really bad and ruined my project. If anyone of you can tell me what product is working perfect for Glowforge, that will be really helpful.
What do you mean by ruined your project? If you mean it did not stick to the material, then it is because of what Jules said: the adhesive is pressure sensitive and you need to use a squeegee to press it down and activate the adhesive. If it is something else, then maybe someone here can help troubleshoot.
