I am in complete love with the look of these curtains, which I spotted in the pages of Skona Hem magazine. The rough linen material pairs so beautifully with the masculine leather straps. To add even more of a masculine edge, the curtains haven't been hemmed and have been allowed to naturally fray.
You could re-create this look in your home by using lengths of repurposed skinny leather belts, or perhaps even leather suspenders. Even better, check eBay or rural auctions for horse tack sales. Leather reins would be a perfect way to get this look.
Of course, this effect wouldn't be quite so lovely if the entire room looked so stylishly unkempt. The crisp white chairs and cheery greenery add balance to the curtains' rougher edge.
