I definitely can relate. You are probably saving major dollars not having a kitchen designer, and you are getting exactly what you want. It's so stressful. Someone posted on here that she kept repeating to herself "it's only a kitchen...it's only a kitchen..." It's worth the pain and the time you are putting in to it. After you've been in the new kitchen a short time you will definitely forget this pain and suffering. I suggest get the granite and backsplash picked out, printing out pix from the Finished Kitchens Blog (google it) Finished Backsplash Slideshow with you when you go shopping. Try to stick to one or two inspiration photos. That helped me so much to show stores what I was looking for, and I was less distracted by other stuff once I had my inspiration photos with me.
Try Google Images searching for key words like bronze sink granite & you'll get a couple pix of kitchens with that combo to see which granites & hardware look good.

You could carve up your 3 biggest questions and make each separate discussion question topic here....like "Any granite ideas for bronze sink?" & someone might give you a great suggestion. Good luck. We are rooting for you.

I'd decide on the granite next. that would depend on the color of cabs, floor and the look you want in your kitchen.

have you researched bronze sinks? asked here for pics? how people like them? is it difficult to clean them?

then the faucet

then the BS - that can usually wait.

Welcome to GW! I'm a relative newbie myself, but this is a great place to be for kitchen friends!

Yes, I am absolutely, totally relating here! We had many decisions made beforehand and I have ended up changing several midstream, or at least worrying and obsessing until it is too late to change my mind again.

Go ahead and put your questions out here and let people help you figure things out. Mostly, what you have left is a personal choice, but if you can narrow it down and post pictures, you will get some good input.

To start with, look at the Read Me thread to see if anything there would be helpful, even though you are past the layout stage. From there, compile your questions and fire away. Pictures are always helpful. There is an explanation in Read Me about embedding them in your posts. It's easy to do once you know how.

There are some good online companies that will deliver sinks, faucets and other items in a matter of days at competitive prices and often with free shipping.

Maybe it will be a good thing to have only 3 weeks to decide, if in fact there is no flexibility in that timeline. No time to continue to 2nd guess! : )

I SO know how you feel. I second guessed myself the whole way through! I thought it would be so much fun and it ended up to be much more stressful than I thought. I remember getting upset with my contractor who wanted me to make a decision on the undercabinet lighting! I thought that was his job. It ended up that wasn't in his bid! Hang in there. I choose the cabs first, followed by the countertops, and then the flooring. If you already have the flooring, the countertops will need to be near the end, followed by the backsplash.

Thanks for the support! You will see me here a lot in the next few weeks.

Welcome!! Fear not---this is a great place for help. You've been really wise so far, it seems. Be sure to look through the FKB and print off a few photos of kitchens that "sing to your heart." For me, it was Redroze's kitchen. I also loved Willowdecor's ideas, even though we didn't end up with marble. And if you post something really specific, like, "What color granite would go best with my cabinet color?" and then include a photo, you'll get all kinds of quick help. And Boxerpups is a whiz at finding the exact look you're worrying over. (Boxer, it's not that I'm trying to give you more work...but I've been a real fan for a long time).
People have asked, "Which knobs/pulls would look best with my granite?" and gotten immediate ideas from others. My kitchen's been done for six or seven months and I still love looking here. I'm always inspired by others' questions and feedback.

just a note on second guessing yourself. That will go on and on with EVERYTHING until the decision can not be changed and invariably (I have found) you will be thrilled when you see it.
a very exciting but frightening time but use the forums. The people here are unbelievably generous with their time and ideas and also see things like a normal person vs designer.
ie function but also the look

This sounds like my life right now. YOu get to a a point where every decision depends on the other decision. The backsplash depends on the counter top which depends on the paint and the hardware finish somehow must figure in the mix.

Now its like which do I lock in first. For example you may love this backsplash but it really doesn't go with white quartz which you really wanted. Now multiply that to the nth dimension and thats where I am at. Every decision has consequencies down the line that I'm not ready to deal with.

The thing is you only get to do a kitchen of your dreams once or if you lucky you get a second shot. We want everything to be PERFECT however they must also go together for the room to be perfect but for each individual decision its so hard to not pick your dream blank because it doesn't go with your dream blank that you already picked

Yes, I can so relate. Isn't it wonderful that you found GW? It has been such a help to me. I made a spreadsheet called kitchen decisions and checked off as I went. It at least made it seem like I was accomplishing something.
