Google Chrome has posted a notice that the Cricut plugin will soon be unsupported. Do not be alarmed, a Cricut update will be released shortly to resolve this issue.
Using Cricut® Cutting Mats
For best performance, use the recommended material types for each of the three mats. Be sure to use the recommended cut set tings for your material type as well.
For even wear across the entire surface of the mat, alternate which end you load into the machine first.
