FAQs About DIY Watercolor Postcards

Do I need to use watercolor-specific paper?
Yes! Regular paper will buckle and warp. Watercolor paper holds paint and water better.

Can I use kids’ watercolors?
Yes, especially for practice or if crafting with children. Higher-quality paints yield brighter results.

What kind of stamp should I use?
Use standard postcard postage (check USPS for current rates). If in doubt, ask at your post office.

Will the paint smudge in the mail?
Let your card dry completely and seal with a fixative spray if possible.
