Oh, okay, may need to clarify some more. If you get a new 2 seater in place of the 2 white chairs, fine, but no blue chair at all next to the 'new' 2 seater. Won't be right with a blue chair too. So what ones are you planning to recover?. If getting rid of part of it, not understanding. 2 different styles placed next to each other won't look right. I wouldn't like old blue fabrics next to new fabrics or next to 2 different styles of furniture. New 2 seater and old blue chair next to each other, not good :)

Have you thought about getting slipcovers made? If you wanted to go with a cottage look white or off white would look good with your rustic fireplace. Don't be afraid of the white, slipcovers that are made well will last a long time, and can be washed even bleached. I have had mine for probably 9 years now. Love that you can wash them. I would skirt the bottom of the slipcovers. I think it would really transform them. You could bring in some blue accents with pillows, etc. Some pictures on your wall with some ocean blues would look nice with some rustic touches like antlers, shells etc.

Congratulations on your new home! Now, go cancel that order! Just kidding. Kind of... I really do think, after reading your posts, that you will be happier with the grey couches. Personally, black couches in general seem very bachelor pad (ish). That said, I know there are gorgeous black leather couches available. For a super modern industrial place, maybe. But beach, or that kind of vibe? I am not sure how you would pull that off over the years. Grey or tan (neither are my own favorite decorating colors, but still) would be oh so much better as a neutral for pulling in different color palettes with pillows and art, etc. if you decide to change up through the years... black might make you feel stuck. After reading through what I have written it seems a bit funny, as black is my personal neutral in clothing, jewelry and the like. But as I look around my home there is no black to be seen. Hmmm. In any event, follow your own intuition here, and don't feel like you have to fill the space before your home is even completed. Especially if you are having second thoughts. And remember, this is supposed to be fun for you! When in doubt, leave it out! At least for the time being.

My last household purchase was new sliding doors to the outside from my dining room. This then led to the building of a deck, new railing on said deck and existing terrace, new blinds as the old window length curtains no longer did the trick, then the paving stone path to the deck from the garden gate, some new planting to accommodate that, AND outdoor lighting for what has now become an alternative entrance to the house! Oh, and painting as well. So I can liken my last purchase to a bit of a triffid - it kept growing! But SO worth it! It has added another room/space to my house, increased light and warmth, added value and created a more welcoming entrance than before. Love it!
