For ease of working it does help if you use row repeats that are divisable into the largest number. If largest is 24 row rep, you could have 2, 4, 6, 8, 12 row rep options but you certainly want balance (don’t want something really tiny offsetting something really big). If you chose something with a 16 or 18 row rep your starting point wouldn’t fit w/in the 24. Not impossible but just more diff to keep track of. Also helps, horizontally, to have a field of sts…moss, seed, etc…to set off the cabling. And sometimes small vertical lines help define spaces (twisted Ks, 2-st cables).
Sometimes best to mock up little swatches of each st pattern you’re planning to do and lay them next to each other. Move them around, alter the no of row reps if necessary to allow for more visual harmony. If you have a cable with 22 row rep and everything else is divisable into 24, you could prob add 2 rows to the 22. You can also chg cables to your liking. Want it taller, wider?
Look at pics of cable combos you like. Try switching out their choices with some of your own.
