There are many sites where you can get free vector art and I’ll be profiling some of them in the coming days. The freebies at DragonArtz are beautiful, abundant and best of all, come in SVG format.
Now just because something is in SVG doesn’t mean it is ready to cut, or even cuttable at all. To use these with your cutter, open them in Inkscape, select object>ungroup as necessary, delete unwanted items, and then recombine elements with appropriate path commands, separate colors, etc. Then save your edited version and import into SCAL.
