I find meandering and stippling quite difficult because of the "no crossing lines" rule. Sometimes I sew myself into a corner and can't get out. One thing I think about a lot is that ANYTHING worth doing (and doing well) deserves and requires a lot of practice. There are only a few born artistic geniuses who don't need to practice. The rest of us need to drudge through and do the best we can. Eventually we get better, and at one point, the process becomes second nature. So have fun practicing. Just remember, nobody is going to sit and evaluate your work in great detail. Just enjoy the process. The rest will come.
