I'm developing an application for iOS and Android and I love the style of the Wunderlist icon, so I want to know if there is any tutorial about how to create this "rounded wooden drawer" effect in Photoshop.
It's nothing more than vector(?) shapes with layer styles. You could take a simple rounded rectangle & add the texture. Then you double the layer, move below the current one and add a drop shadow to the above layer. Maybe it's just a mirrored linear gradient on the lower layer. The rest is bevel & emboss. It could also be that the white highlight on the lower edge is a third layer with - again - a (white) gradient.
