Couldn't you have some cupboard doors made to cover the shelving, maybe of painted plywood (cheap and nice)? They don't need to be fitted kitchen units and so wouldn't be as deep. You could paint them the same colour as the walls, and everything would be hidden.
Open shelving does look nice on kitchens but it gets dusty of course. How about putting stuff in storage jars and boxes. Use some of the open shelving from Ikea and you can buy hooks to hang stuff. Check out Pinterest there are some great ideas on there.
You could order a narrow 8' cupboard with doors from Jali.com and assemble and install it yourselves ! There's an online design guide on their site so you can work out exactly how large you can make it and go from there !!
We have a narrow set of open shelves which go vertically at the end of the run of cupboards. They looked awful before but my sister who has a good eye for these things arranged my cookbooks on each shelf by colour with one or two objects that match the colour eg vase teapot cake stand etc. it looks quite arty and pretty now! I put a photo on Instagram will try and link in the morning
If it is mainly your cups/glasses etc then I think the cheapest option to make it look good is to replace with plain glasses and eg white cups from IKEA so they are matching or you could go for a vintage mismatched look? A long plate rack would work for crockery and as its stacked side-on it doesn't matter if it matches or not.
Can you create storage elsewhere, on a trolley or unit for this kind of thing (Expedit is good for kitchen stuff)? DO you have pics of your kitchen?
I had open shelving in my last kitchen. I found the more random items were the nicer it looked. I am going to do the same in this house. If you have the depth just deliberately mismatch. Some crockery, some baking items etc. TKMAXX can have interesting useful kitchen items. Also, this time I am going to ask a glazing company to make sliding doors to go in between the shelves. Shelves need to be routed before they go up.
ps always check posts.......crockery was almost cockery
