Potentially silly question alert. I have a number of icons. Do I have to keep them in a corner together? With candles and incense?
No. You can do that, but you can also designate a "corner" where you will pray, keep one or two icons there, and put the others wherever you'd like. Candles and incense are nice, but also not necessary everywhere.
I keep two candles in my "corner" (it's really not a corner, but the wall facing East), but I rarely light them, instead I keep an oil lamp burning before them. I don't use incense. Not all of my icons are in the corner, but only a few. Elsewhere in my living space, I have a couple of icons which are just on the wall or on a shelf, etc., but nothing fancy, and most of the icons I've acquired over the years I keep in "storage" except when "seasonally appropriate". There's a lot of freedom when it comes to things like this--there are some basic "common" elements, but a lot of leeway.
