What a difference the window treatments can make. New York designers Tocar Interior Design have a great batch of before and after shots on their website. And one thing we noticed that packs a real punch in the afters are the window treatments...

The treatments in the room pictured above are most effective. What was once divided with a center panel is now treated as one large window opening with drapes flanking each side. They're hung higher than before, giving a real sense of size and openness to the room. These treatments practically create an entirely new architectural detail all on their own.

The shade in this kitchen, we think, works better than the fully exposed fan-shaped window. The fully exposed window chopped the kitchen into pieces, while the shade creates a horizontal element, which works to carry through the line of the upper cabinets.

This living room looks like it could be in a small apartment, where svelte (after) is going to work better than frilly (before) any day. The soffit above was transformed into a tidy curtain pocket instead of a broad surface covered in pleats of fabric.

Formality is notched up in this dining room with a dark stain on the wood plus drapes that flank what was once french doors. It appears the door/window was changed in the after photo, but even with the same door these treatments would work well. By the way - we love how the shelf nook in the foreground was turned into storage for stacked firewood.
