Decide whether to install door catches. These will secure your doors while they are closed. Magnetic door catches are most often used. When your door closes, a small metal plate on the back of the door attaches itself to a magnet on the cabinet frame. You will hear a slight clicking sound as they make contact. Two additional styles that provide a smooth operation are spring-roller catches and friction catches. These catches are silent when they latch.
Kitchen knobs, pulls, and hinges have come a long way from the traditional styles that have been available over the years. No longer are homeowners limited to plain, simple, and functional. Instead, functional and pretty can now go hand in hand. Today’s styles include finishes in antique copper, iron, nickel, polished chrome, aged bronze, polished brass, glass, stainless steel, and antique brass. Additionally, a variety of knobs, handles, and pulls are available in ceramic styles.
The quick answer is yes, you can change the hinges. The hard part is what type. Cabinet doors have lots of different configurations.....full overlay, partial overlay, inset, etc., etc. The hinges have to fit the door style. There are hidden hinges that screw to the cabinet framework without major holes, and there are European type hinges that require a large hole to set the hinge into. Go to big box and look at the hinges, what is available can be mind boggling, until you understand the type of door you have.
My go-to shop for all of my hardware needs is D.Lawless Hardware – I’ve been using hardware from there for a while now and it’s always the best quality at the lowest prices. They sell so many other awesome products too. Everything from knobs and pulls, drawer slides and systems, to wood appliques, trim, DIY, craft supplies, outlet covers, and so much more! 
Consider proportion, balance, aesthetics and function when deciding upon the size of a knob or pull for your kitchen cabinetry. A large cabinet door or drawer needs a larger piece of hardware, or maybe two, for proper functionality, but a smaller size knob or pull is appropriate for a smaller door or drawer. A good rule of thumb for traditional or transitional style pulls is that they should be about one-third of the length of the cabinet drawer. Drawers larger than eighteen inches wide may require more than one pull or knob. However, more contemporary designs call for longer pulls that are at least two-thirds of the length of the drawer or cabinet door. 
2) I also note that it does not take long before doors start to sag & the gaps become irregular. Not hard to fix just lie on your back, take all doors off, then tighten everything & replace – then take a cold shower you will need it! It seems the cup sections remain well fixed but the fixing plates on the inside of the cupboard sides just work loose. This ought not to happen but it does & with all the concealed overlay hinges I have seen. Is there an answer? I suspect the hinges are under rated, 2 hinges for doors that typically are nearly 10Lbs may be the reason. Can you please comment.

The importance of selecting quality hardware is impossible to overstate. As with many parts of our home, hardware is an investment. We have all seen cabinet knobs that loosen too easily and hinges that wear out. Because hardware is going to receive the bulk of a cabinet’s wear and tear, investing more in it is ultimately investing more in the life of your cabinets.

And starting to play with my new HVLP turbine spray system.  (Whenever I say HVLP turbine, I think of the movie “A Christmas Story” and how Ralphie describes his Red Ryder BB gun – “an official Red Ryder, carbine action, two-hundred shot range model air rifle.”  I think I’m equally enamored with my new gun, even if it doesn’t have a compass and a stock. 😉
The chrome and stainless steel can vary some too, but usually not as much, and as often as nickel.  To be safe, get samples from different brands and compare the colors, or get all the hardware that you need for  a single room from one manufacturer.  It’s ok if the nickel in one room doesn’t exactly match the nickel in another room.  It only looks mismatched if the different nickel finishes  are right next to each other in the same room.

Accessorizing is the most important part of any outfit. A little glimmer, a little glam or maybe something unexpected and modern can make an ensemble.
