Oh please stick with it. Your colors are so yummy. At least you are doing the blocks with different colors to break it up a touch. Think of it this way, you are almost half way there!
But I too get bored with repetition. I am currently working on the PP border for my sawtooth cat quilt and it is getting a bit tedious. But I am sticking with it. I have other projects to help break up the monotony, like a handquilting project downstairs and pretty soon something on the longarm. I think it helps to have more than one project going at a time. But usually I have concurrent project in different stages. I try to stick with piecing one project until that piecing is done. But have been known to break up the piecing with a quickie, like a block swap on this board, or sewing up some crumb blocks or working on a scrap log cabin that is has been off and on for years. Mostly due to needing to build up the scraps and cut them into the needed logs.
