Reclaimed logs as bookshelves - This would not be horribly hard, and could be gorgeous.
LOVE this corner shelf via Not just a housewife
Barnboard corner shelf I need this by the kids bathroom. Maybe one with doors (towels, soaps, etc)
corkscrew willow, coral, & shells
Super simple decor with shells and sand candles.
