You can shop a wide selection on Walmart.com and in select stores. The category includes flat river rocks, smooth pebbles, and flat glass gems that work well for painting and DIY decor.

• Search for terms like “flat rocks for crafts,” “river rocks for painting,” or “glass marbles.”
• Use filters to sort by size (e.g., 1–3 inches), color, and pack count.
• Bulk packs can be helpful for classrooms, parties, or kindness rock projects.
• Choose delivery or store pickup where available, and check local store availability online before you go.
• Review product photos and size ranges to make sure the shape and smoothness match your project.

In crafts, you’ll often see them described a few different ways, and each term points to a slightly different look or use.

• River rocks/pebbles: Natural stones with smooth, rounded edges and flat faces—great for painting and garden decor.
• Painting rocks/craft rocks: A general label for hand-picked stones with flatter surfaces for artwork.
• Flat glass gems/marbles: Glass pieces with one flat side, popular for vase fillers, mosaics, and small designs.

On Walmart.com, check the product titles and photos for details like size range, color, and finish, so you can match the surface to your project’s needs.

Guidelines can vary by city, park, school, or neighborhood, so it’s a good idea to check posted rules or ask for permission first.

• Place rocks only where it’s allowed—community rock gardens or approved events are usually best.
• Avoid protected habitats, waterways, and private property without permission.
• Keep designs durable and tidy; avoid loose embellishments that could detach outdoors.
• Use products as directed by the manufacturer and allow items to dry fully before placing.
• If an organization requests removal, plan to retrieve the rocks respectfully.

A quick check with local guidelines helps ensure your kindness rocks bring joy without causing issues.

The right size depends on your design, display space, and who’s painting.

• Small (about 1–2 inches): Simple icons, patterns, or magnets; great for quick crafts and kids.
• Medium (about 2–3 inches): Quotes, simple florals, and beginner-friendly scenes; a popular all-around pick.
• Large (about 3.5–5 inches): Detailed landscapes or porch/garden statements; fewer pieces cover more area.

Look for stones described as “flat” or “smooth” to make outlining and lettering easier. If you’re unsure, a mixed-size pack can help you test designs and find your preferred surface.

Availability can vary by location, so checking online before visiting is helpful.

• On Walmart.com, select your store and look for in-store stock indicators or curbside pickup options.
• In stores, painting rocks and flat pebbles may appear in the arts & crafts area (craft surfaces or floral decor) or seasonally in the garden section.
• Use aisle information from the website when available, or ask an associate for help.
• While you’re there, consider picking up acrylic paints, paint pens, stencils, and a clear sealer to complete your project.

If your store is out, you can order online for delivery or pickup where offered.
