Raindrop is a cross between a bookmarking service like Pocket and a scrapbooking service like Pinterest. If you need to keep track of inspiration and create a wishlist for furnishings, then this is definitely worth checking out.
Another option worth checking out is Evernote. You can create different notebooks where you can save clipped websites, images, and create notes to keep track of your project. You can also collaborate with a partner through shared notes, which could be handy.
