One thing to think about if you are doing straight lines, i.e. crosshatching.......I made a piece that I deliberately made the lines not match up. When it was judged the judge said it should have been straight. What can I say....I did not want them straight. One judges perception (her's) of how crosshatching should be done vs another judges perception of being creativite (mine). Haha
So my point here was....if you were to decide to crosshatch between the motifs you already have, take care to get them to line up good. :-)
