I had a prior post where I gave a rather contorted procedure for filling in the fonts that you draw with Cricut markers, gel pens, etc. Today I had a better idea. Find fonts that already have a “fill” that works with the Cricut. So I tested a bunch of fonts with my gel pens and when one seemed promising, I reduced the size until the fill looked solid. Some look really nice with the crosshatch showing, as well. All of these are freebies from either fonts101.com or dafont.com.
Keep in mind that these take a long time to draw, so plan ahead. If you want to use markers instead of gel pens, there are many more options, or you can use the fonts above at even at larger sizes. Also see this previous post about single line fonts.
