When working with vinyl and other similar materials, much of the finished product depends on your techniques. I have made several thousand items with adhesive vinyl so I have become quite fluent with application of the material. I can often tell what will adhere well and what won't and how to apply to certain contoured surfaces. Again, this ability comes after thousands of applications and practice. When we first bought our Cricut Explore I spent about a month just learning how to apply vinyl properly, reading Facebook Groups, and doing research. Rarely did I ask a question because if I looked for just a bit, I learned there were already people asking the same questions. One of the things I learned was how to avoid bubbles in my vinyl. Here's a video on how I apply vinyl without a single bubble.
