I believe that you can work on something long enough that you get tired and take it out on the project by not liking it anymore ... alwalys put it away for a few days to allow yourself to rest up and see it though rested eyes. usually it improves. I have made cloths, quiltsor even curtains that I just hated when finished. but when i looked at them several days later I fell in love with them or at least could tolerate them,
