I used this same method to cut vinyl window clings for my son's car with the Cubs Logo, and his college logo for my car. I also made a Dallas Cowboys window cling for a friend. Just make sure when you are searching for images that you get something with decent resolution.... I'd say nothing less than 200 x 200, but preferably 400 x 400 or better, this particular image was over 1000 x 1000.
Have fun creating and as always I'd love to see what you made!
If there are any techniques that you'd like me to use in a video, please let me know. I'm enjoying the requests and will try and get them uploaded as quickly as possible.
