逐步说明

1

步骤 1: Paint the terracotta pot

Wash and dry your rock. Paint the lower quarter of the rock with terracotta or brown paint to create the pot. Add a slightly lighter band near the top of the pot for the rim. Let dry completely.

步骤 2: Paint the cactus body

Paint the upper three quarters of the rock with medium green paint for the main cactus column. Add a darker green shade on the sides to give the cylindrical body a rounded, three-dimensional appearance. Include two smaller arm branches curving outward from mid-height.

步骤 3: Add the spines

Using white or light yellow paint and your fine brush, paint short radiating lines all over the cactus body and arms to represent spines. Work in rows from bottom to top. Each spine cluster should have three to five short lines radiating from a central point. This is the most distinctive cactus feature.

步骤 4: Add cactus flowers

Paint small pink or yellow flowers blooming at the tops of the cactus arms and main column. Each flower is a star shape with rounded petals. Add a tiny yellow center dot to each flower. Cactus flowers are a burst of color and add great visual contrast.

步骤 5: Detail the pot and seal

Add small curved lines on the pot to suggest the texture of clay. Add a shadow below the pot rim with a darker terracotta line. Once everything is fully dry, apply clear sealant to protect your desert cactus rock.

步骤 6: 添加RoxGeo代码

在岩石的底部或背面写上 ROXGEO.COM，后面跟一个斜杠和你岩石的唯一代码（例如 ROXGEO.COM/ABC123）。这让发现者可以直接访问你岩石的个人资料页面并记录他们的发现。如果岩石太小而无法写下完整地址，可以写 #ROX 后跟没有空格的代码（例如 #ROXABC123）——这样简短，容易在Google上搜索，并直接引导到你岩石的旅程页面。使用细尖永久性马克笔或丙烯颜料笔，并用透明清漆封住，以确保代码在雨水、阳光和冒险中保持可读。

实用小贴士

选择一块形状适合你设计主题的石头。
白色底涂层使所有颜色更加鲜艳。
在添加下一层之前，让每一层完全干燥。
用透明密封喷雾保护石头，使其在户外也能持久。
对于底部的RoxGeo代码，请使用防水的永久性马克笔（如Sharpie）或丙烯画笔。在代码上涂抹2-3层透明密封剂——这可以让它在雨水、阳光和多次处理下保持可读性，持续数月。
在你的岩石上写上#ROXCODE（例如#ROXABC123）可以通过谷歌搜索轻松找到它。我们积极优化这个标签，因此任何搜索它的人都能快速找到你岩石的个人资料页面。
完整地址ROXGEO.COM/CODE将直接带领发现者到你的岩石卡片上，在那里他们可以看到它的完整旅行历史、之前的发现者和每个停靠点的照片。
