New - Squiggle/Doodle Artwork

I did a couple doodles this last weekend.  The original drawing was with a black pen, on paper.  I used to create these doodles all the time when I was in high school & college.  The way I create them is by drawing one single continuous line that zig-zags around, sometimes just creating patterns, sometime forming recognizable shapes or objects.  This one (below) was started in the center with the heart.

It's a fun way to doodle, and takes a bit of planning ahead so that you don't accidentally doodle your way into an area without a way out.  (if that makes any sense)

Here's my doodle after I cleaned it up a bit and colored it in:

And, here is a "blank" version of it - in case you are interested in using it or interested in coloring it in a different way:
