Folding small blind so you can steal later

When the table folds around and I'm in the small blind, I will often fold not only weak, but marginal hands. Hands that might be favored over a random hand, like Kx or even A-rag. I do it hoping that the big blind will notice now and give me more credit later and let me steal when the blinds are more worthwhile.

I haven't seen this topic discussed much on this forum. Is this a common strategy, or am I just imagining that this works?
