Today, in my internet adventure…I stumbled upon a fabulous Scrapbooking Blog with a VERY helpful Cricut Cutting Guide. Joy at Obsessed with Scrapbooking has allowed me to post a link to her chart, that you can download and print off to put near or on your cricut. It is a helpful tool, in knowing the BLADE, SPEED and PRESSURE for different types of paper!
Go here to download/print/view the Cricut Cutting Chart.
Hope this helps you with all of your Cricut Creations!
