i want to recreate one or more of the things i do in mspaint, in real paint.  
for instance, 
i'm thinking the easiest way to do this as perfectly as i want it is to re-size the image and print it out--on multiple sheets of paper
lay the paper over card-stock (or something similarly thick) and cut out the lines, making a stencil.  
fasten the stencil onto a canvas (with painter's tape?  or what?) and paint in all the solid lines.  let it dry, mix all my paints, and fill in between the lines.  
if i get sloppy, which i'm sure i will, i can just wait for the whole thing to dry and re-apply the stencil to go over it.  
 
would this work, or am i not considering something?
