At last we've found a magnetic chart board that works well, is made in North America and is reasonably priced  . . . Here's an example used with a lace chart.  You can also bracket repeats (like the one between solid black lines on this lace pattern) with magnets placed vertically. The stand is light weight and folds for convenient storage in your knitting bag.  Kit comes with 8 x 10 board, 3 black magnetic strips, a magnetic ruler and stand.  Use the board to keep your place in lace and cabling charts or line-by-line instructions.  You'll love it!
