I agree with a sampler because you don't have time to get bored doing the same block over and over and there should be plenty to choose from that you can do with those 3 colors, and every block doesn't have to be different either, maybe just pick 4/5 that appeal to you and go for it. You don't have to keep it forever if you don't love it when you're done, put it in the closet for when company comes and you need extra covers or a pallet and start on another one. I'm working on a blue sampler ( a year already) for my bedroom and I'm going to make curtains to go with it. As much money and time as I've put into it I sure hope I love it!
