You say “Once we’ve done that we can @import “blueprint”. Unfortunately I skipped to the “What To Do” section (I always find it easier to follow once I have something working), unfortunately it misses that bit so I had to look at the online documentation to get it working (http://compass-style.org/examples/blueprint/grid/two_cols/).
One thing I was thinking whilst reading this section is whether its talking about wider topics? Best practices (or just tips) with multiple column layouts, best practices when working with grids, gotchas with compass/blueprint, debugging/resolving oddities you get when using them. Not sure if this is the sort of content your trying to cover, or whether it’d be best to cover here or seperately, but it just occurred to me that it might be useful.
