GRAPHS. I don’t use graph patterns, just written ones, but having both right there in front of you is a total life saver! Seeing it in graph form is a “magic trick” I use to get a good picture of the pattern.
PRINTING out the pattern is a huge help too. Even if you are using a written pattern, if you have the graph printed out right there you can highlight to check off the rows you’ve completed.
KNITTING LOGS: Another trick of mine is the free patterns on the back of the yarn wrappers, or old newspaper patterns etc, I keep in a folder in a plastic sleeve or I just paste or tape them to paper, I have a 3 hole punch thingie I use to keep them in an old school hard plastic folder. I have extra pages where I write down which pattern, what gift when to whom, the date and how much yarn used, stitches etc or other tips for that pattern.
PRINT PATTERNS never rely on saved patterns in your computer. You never know what might happen. I print them out regardless, that way I always have them. Its much easier and less confusing when I am looking for a pattern to flip through a folder of patterns on paper than trying to find it in my computer some place.
