Every drawer pull in my kitchen is 2-7/8" hole center which is certainly not a common size. I found some 3" that I like (thinking mine were actually 3" center) but unfortunately (and ever so obviously) they do not fit. I can't find any handles online in my current size so I'd like to change my cabinets to 3". The obvious issue with that is that I will have visible holes in my cabinets because the new handles won't cover it up all the way. Is the any inventive way that I can overcome this issue without unnecessarily replacing my cabinet doors? Also, I'm open to keeping my existing non standard size if I can actually find some. Right now that seems impossible though.
You can use color matched wood putty to fill the holes. They'll mostly by hidden by the handles, so it may not look as bad as you'd think.
