Strathmore - Blank Watercolor Postcards

Blank Watercolor Postcards

Transform watercolor paintings into mailable gifts on sturdy postcards

Cold press watercolor paper that travels through the postal system, Strathmore designed these postcards to handle both paint application and mail handling. The 140 lb weight provides enough body to resist warping under wet washes while maintaining flexibility for postal sorting equipment. Acid-free paper stock ensures your painted images won't yellow or deteriorate during their journey to recipients.

The textured cold press surface accepts watercolor, acrylic, and gouache with proper tooth for paint adhesion. Front surfaces remain completely blank for your artwork, while backs feature standard postal markings: address lines, stamp placement guides, and message space. This dual-sided design eliminates guesswork about proper postcard formatting.

Each 4" × 6" card meets standard postcard dimensions for consistent postal rates. The 15-sheet pad format keeps cards protected until you're ready to paint. These work equally well for quick gift paintings, plein air studies you can mail from location, or ongoing correspondence projects where you send original artwork rather than printed cards. Paint, address, stamp, and drop in the mail, no envelopes, no protective sleeves required.
