So I am working once again at attempting to learn Japanese. Who knows how well or far I will go this time. But while I was working on aides to help learn characters and words I got tired of making guide lines by hand after the 2nd card. Here is a template I made very quickly in Photoshop. Feel free to use if you find it helpful. Image as a jpg.
Also made a static page for the template.
This link to the PSD file should work, let me know if it does not.
I added a 8.5 by 11 template for card stock. It is centered on the page so should be able to be printed on both sides.
