I made this today, although the SVG has been cooking for some time now
This card involves cutting, drawing and scoring with Cricut explore.
I still don't know how to group objects in Illustrator so they are grouped after importing to design space, so you must change the function to score the lines and to write the letters and curves.
I've made it easy:
Green lines = scoring
orange lines = write
I bought a Midori Traveler's Notebook a couple of months ago - there's an amazing stationery store in San Francisco - I just love it!. Surfing through midori's site (http://www.midori-japan.co.jp/tr/english/) I came across Kraft Paper Envelopes and decided to make my own, but with a twist.
