Help with pattern with letters

Recently I’ve started knitting this pattern with letters in it. The letters only go about 1/3 of the way around the row so my question is; should I cut the yarn when finishing each row, or should I just keep the yarn loose and use the same thread the whole way?

What pattern are you making? Can you give us a link to it?
Is it knit in the round or flat (back and forth)?

Thank you!
The pattern is on paper so i dont have a link, but its knit in the round.

You can often knit letters using intarsia but in order to do that in the round you either have to do short rows or carry the yarn around.

If the project is small carrying the yarn can be done but the larger the project, the more painful this is.
What method does your pattern recommend? What is it you’re making? Can you use duplicate stitch for the letters?
