I wonder whether that is not 16x16?
TBH the last time I had any [brief] involvement with icons they were only 16x16, drawn in Paint, using the default colours. Using that method, the '1 pixel line, 1 pixel in' idea might make more sense
Now, from a quick read, the default is to create at 256x256, in 256 colours, then let the conversion software do the rest. Using this method, each size would need to be created then the line added with appropriate pixel size and spacing.
