If I find a pattern that I know I will use over and over, I write each row on an index card, punch a hole in the top left corner and attach the cards with a binder ring. You can then flip through as you continue each row. On the last card (well, the card before any finishing instructions) I note how many repeats of the pattern to make (actually, I do all this on the computer and laminate the cards - that way I can tick off any repeats with-in the rows, or if there are sections of the pattern that are straight repeats (ie. knit 8 rows...) ) I will also usually start the cards with a pic of the finished product, then any special instructions, then onto the pattern rows.
hope that was clear!
