fun, pretty, difficult
These are okay. Kind of a fun art project.  The magnets are too complicated. Maybe best to just use the straight line magnet (very very fast after applying paint).  You have to use black undercoat. The bottles are really hard to tell apart and have nondescript names like "aurora borealis" . You'll need to put swatches on a paper and then label the bottles pink, green, purple, etc. I accidentally made 9 nails pink and 1 green. This was fun and did look quite pretty. I recommend but please be prepared to practice and re-do. A flat surface helps for the magnets.
