When I upload my SVG to Cricut Design Space, it's TINY! What happened?

This seems to be a similar issue to the "too huge" problem I just mentioned, but with a different fix. Open your file in Inkscape, go to File > Document Properties, and make sure your Display Units are set to "in" and your Scale is set to "1.00000." If they aren't, change them following the instructions in the video linked above. If they are correct, click the "Resize page to drawing or selection" button in the Custom Size area of the Document Properties, save your SVG, and upload it to Design Space again. (Note: If you do not see the "Resize page to drawing or selection" button, it means you are using an older version of Inkscape. Please update before continuing.)
