Charts use a square to represent each stitch and a symbol inside the square to indicate how to work the stitch. Though there is no universal set of symbols, each pattern that uses a chart will give you a key to reading it. Always begin by finding the key to the chart. Generally, if the first row is a right-side row, charts start in the bottom right-hand corner and read to the left. The second row is read from left to right. (If the first row is a wrong-side row, the first row of the chart reads from left to right.)
The most important thing to remember about charts is that they represent the pattern of the knitted fabric as you're looking at it � the right side of the fabric. This means that on wrong side rows (from left to right) you must purl any stitch that has a knit symbol and knit any stitch that has a purl symbol.
You can always scan and enlarge it ,or if you not very good at that sort of thing ,much like yours truly ,I'm sure they will be able to do it at a copy shop or your local library .If you can do this and then work it out from there you can then write the repeat pattern down and refer to that rather than the chart .
