How to Stroke a Path in Photoshop
Make shapes or freeform paths come alive in Adobe Photoshop by adding a colored stroke to the path or shape. You have control over the width and color of the stroke you apply and can choose the tool effect as well. When working on an existing file, experiment with strokes on a new layer of the document until you reach exactly the effect you seek. Then flatten the layer into the document.
Launch Adobe Photoshop and open a new document by choosing "File" from the menu bar and selecting "New" from the drop-down menu. Alternatively, open an existing file and create a new layer on which to work.
Draw a path on the Photoshop document using any of the shape or drawing tools in the toolbar.
Set a color in your foreground color square at the bottom of the toolbar.
Click on the Paintbrush Tool and select a brush profile and size for the stroke.
Click on the Direct Selection Tool, which resembles a white arrow. Then click on the path.
Right click and choose "Stroke Path."
