In harvest moon ds cute i missed the ornament box and the kitchen... HELP?

You don't need the kitchen to get married so I'm sure that's not why he rejected you. It takes around three or four days for the shopping network to change products. If you are wondering if the shopping network will sell the kitchen and ornament box again then yes it will. If he rejected you then maybe you haven't completed all the other requirements. Once you have a red heart and a big bed you also need to save at least 60 harvest sprites and see all four of his heart events before you can get married. Once you've done all that he should accept your proposal. Keep in mind if you propose to Skye things are different then a normal bachelor. Even if you've done everything right he doesn't accept your feather when you offer it. He says something like "Are you going to give that to someone else?". Then you find a note at your house as soon as you walk in. When you go to bed that night make sure the blue feather is in your rucksack otherwise it won't work and you'll have to try again.
