Advertise your ice cream with a postcard by including mouth-watering, close-up shots! This customizable postcard from Canva uses a collage of three photos side-by-side. The title is set in gold typeface below against a simple dark background, followed by details in white. You can upload your own photos through Canva’s drag-and-drop feature, and style them however you want—with the editor, you can apply filters, crop to desired size, and choose the layout and number of photos in the collage.
