-Photoshop (I used version 7, but any version would work provided that it has the Burn and Dodge tools)
-Heart Custom Shape (should be included)
Instructions:-Open a new image, 3 inches by 3 inches, resolution 300 dpi, with a white background.
-Set your foreground color to Red: 164, Green: 136, Blue: 96.
-Choose the Custom Shapes tool, and select a Heart Shape. Change the Shape Color to White. Draw a white heart shape in the upper left hand corner (leave room for another one in the lower right hand corner). Duplicate that layer (Layer>Duplicate Layer). Drag the duplicate layer to the lower right hand corner.
-Select the first heart by CTRL+clicking on the layer in the layer palette.
-Select the background layer. Then copy the selection (Edit>Copy).
-Next- without doing anything else- go to Edit>Paste. The selection WILL disappear! This is supposed to happen.
-Repeat the process for the layer titled Shape 1 copy.
-Delete the shape layers by dragging them to the little garbage can in the lower right hand corner of the layers palette. You don't need them anymore.
-Hide the background layer by clicking on the little eye next to the Background layer in the Layers Palette.
-Select the layer titled Layer 2. This should be the brown heart in the lower right hand corner.
-Choose the Dodge Tool (looks like a push pin in the Tools Palette). Select a fuzzy edged brush. Use a large brush size- I used 60. Color just around the edges, varying how far towards the center you color. You don't want to completely cover the heart- leave the center the original color.
-Repeat the process with Layer 1.
-To check your progress, make the background visible by clicking on the box where the eye used to be.
-Next, select the Burn Tool. The Burn tool looks like a little hand, and is located under the Dodge Tool. Right click on the Dodge tool to bring up the tool menu and to select the Burn tool.
-Hide the background layer like before.
-Using a fuzzy edged brush, with a size smaller than what you used for the Dodge tool (I used 40), lightly darken select areas along the edge of both Layer 1 and Layer 2.
-Make the background layer visible.
And you have now successfully 'chalked' two hearts! Chalking is great for tags, torn paper, embossed backgrounds, whatever you want to use it for!
