Tired of losing your spot in that complicated pattern? Here you go: try Highlighter Tape. Use a strip to mark the current row on your pattern or chart, and you won't spend all your time trying to find your spot... no need for marking things up with a pen.
It's removable -- without residue! -- and reusable, which means that one of these rolls will last for ages. (Just a few pieces can get us through an entire cabled sweater pattern.) It's transparent and easy to apply. And when you're done, just pull it off and put it on the next pattern in your queue. What a clever idea!
An indispensable tool when it comes to complicated charts.
