I do not see velvets and silks for a kitchen sink window sorry. There are plenty of gorgeous fabrics around with beautiful damask or geometric pattern that are striking, that could be found in a faux silk or linen. Velvet is something that I would never put in a kitchen. But it is your kitchen.

My 2¢ worth: first of all replace the dark blinds with translucent cordless single cell blinds in ivory or off-white--they let light through and provide privacy + some insulation from cold or heat. Clean, crisp look.That alone will brighten up this space. #2: clear the counterspace!--so much clutter! Where to put all these appliances that get little daily use? Get yourself a ss 24x20 or larger cart on wheels (see Amazon.com--Seville classic ss cart) and store little used, bulky appliances on its shelves--and roll the cart into a nearby coat closet--out of sight and way-- to be wheeled back when needed or individually carried back as needed. 3#gorgeous blue tiled walls.Don't touch them. #4:Walls: keep as is if off-white--not same as trim white white.Just a fresh coat needed.To make it "disappear," paint the radiator the same color as the wall behind it. #5Keep the white trim white--looks bright and clean.Keep kitchen door white. You might want to stop here and make no further changes #6Cabinets: I like Gast pic above on right, but too much blue for your blue-tiled kitchen...IMO. I'd go cooler and lighter...consider the light gray of the beadboard in the Gast pic above right. Beautiful hue. Don't go for the white white everyone clamors for these days.Too stark for your kitchen and too contrasty with the blue tile, too country kitchenish. #7. cabinet hardware: Look like glass knobs in pics. Go for knobs/pulls like in the Gast pic above--or similar in pewter or ss, my preference. Those "modern" ss bar handles don't work with your cabinets. #8 the round table is not a good fit against the wall. Get a small sq or rectangular ss or butcherblock-top table for that spot. Chop off the top tier of your chairs to shorten....and match their tops as they are now so's won't appear to take up so much visual space and still remain comfy--don't replace w/ uncomfortable stools.Keep white. #9. Do away with wood valance over sink window.Too country. #10 Countertops--solid color Corian type or laminate--depends on budget--don't want busy stone textures of quartz, etc. Consider a medium value cool gray. (Or maple butcherblock?). Can't see color/texture of floor.... hope some of this helps. Good luck! lisianthus' pic tho nice is too busy-cutesy for your minimalist aims IMO

Hi catbox/emerald18 - your kitchen is absolutely stunning - I love it - mostly because your style is the same as mine - only the tiles I've chosen are Henley Cool from Topps Tiles (sage green/blue). I've also had a few moments of indecision but I've had a picture and sample of the tiles pinned up for months and I still love them. I'd chosen matt slab style kitchen door fronts but I might be convinced by your photo to change to Shaker. I am also going for the wood worktop but can't decide whether to have a Belfast sink or not. What sink did you choose? I also can't decide on a splashback, but like white painted brick + something more cleanable by the sink and hob. Once again, I love love love your kitchen - I'm pinning the photo of it up with my tiles picture in case I get future wobbles about my dream kitchen

There's alot of warm tones there. I agree white cabinets would look great. I'd consider white walls too. From there you could accent with almost any color you like.
