Sorry I misunderstood your concern.
If that's what you're worried about, then you need not be worried. The SnugFit is pretty 'stretchy', I don't even notice it when I put my feet in the footbox of either my older Warbonnet ElDorado or the new BlackBird. No different than laying diagonal in a Trek, ENO, TTTM, etc. The quilt just forms to whatever.
