I would definitely put the appliance pulls on the DW and fridge drawers. Unlike your cabinet drawers which are on slides and so easy to move, the DW and fridge drawers almost have a suction action to them which require a "tug" to open. I have never checked this but I wouldn't be surprised if the screws on the appliance handles are actually bolts and so are heavtier than the drawer pulls and are built for the heavier pull action required. Using the 12" ones would give a uniformity to your appliances. I have a bank of 15" drawers, a bank of 19" drawers and 2 banks of 30" drawers which are shaker style. I have the same not quite 7" pulls on all of them with only one on the 30" drawers. They are all centered in the middle of the drawer. I know that some people center them on the top narrower drawer (cutlery) and then raise them to be set higher on the wider bottom two drawers. That drives my sense of symmetry up the wall. P.S. what do you mean centering them vertically?

I think you should go for them- they are beautiful and unique. I am a firm believer in doing something fun for pulls. When I'm in a kitchen that does fun pulls, it personalizes it a bit more. I'm not sure why your kitchen is considered Victorian (I mean this in the humblest way, I trust it is considered that, but just in my ignorance of current kitchen style wouldn't have categorized in that way) but that style of pull would definitely fit with shaker style. It wouldn't fit with 1930's style which was more stream-lined and art deco. If you wanted to do that, although I know you don't like them, I would do green glass pulls (you can actually do green glass handle pulls too). The link below is to a kitchen that has similar cabinets and counter top and goes 30's. If you were going Victorian, I actually think the style would work with it, while it wouldn't be considered high Victorian, remember Victorian style spanned a long time and includes arts and crafts and eastlake is part of this category. Also remember, if you look historically, the Victorians didn't paint much of anything white- they couldn't get a real white color, it was more brownish because they used Linseed oil as a mixer- so again, go with what you love and don't fret about matching. It's impossible to do accurately. Yeesh sorry for the mini-history shpeil (speil? speel?) but that's one of my favorite parts of decorating. Bottom line, you love them and you'll love having them, so I say run with it! Here is a link that might be useful:

I went through this dilemma. My cabinetmaker told me that shaker 5-piece drawer fronts are made two ways: most commonly, the center panel is a thin piece of wood, sometimes just 1/4" thick and flat on both sides. In the other option, the center panel is actually a reversed raised-panel, with the flat side "out" and the raised side "in". In that case, it's a full 3/4"+ thick. She advised that it's better to have the pulls in thick material (especially for big heavy drawers) so in the first case they should go in the frame. We have the reverse-raised-panel type, so ours are in the centers.

The stainless steel attaches differently from all of the others. I compared the installation pdfs, and all of the fronts - like yours - are placed squarely on the front. The stainless steel - probably due to the weight - is bracketed over and around the sides. So it poses a problem on the inside of the drawer. The panel bracket is shorter than the BLANKETT overhang (for lack of a better description) but the BLANKETT pull still has to fit over the stainless bracket, and it just doesn't work. I just received an email from IKEA customer service and they said BLANKETT pulls don't work with SEKTION at all. Now, that is a lie, because yours work perfectly! So, I am in one of the IKEA nightmares I have heard about. I will take your suggestion to my contractor. Hopefully it will work. I read in another post that someone did that to their 15" BLANKETT pulls.
