逐步说明

1

步骤 1: Paint a sandy ocean background

Wash and dry your flat rock. Paint the entire surface with sandy yellow or beige paint. Add a thin strip of light blue at the top of the rock for the sea. This background sets the beach scene before the crab is painted on top.

步骤 2: Sketch and paint the crab body

Sketch an oval or rounded trapezoid shape for the crab body in the center of the rock. Paint it bright red or orange. Add a slightly darker shade on the edges to suggest the dome-shaped carapace (shell). Two small eyes on stalks can be suggested as tiny bumps at the front.

步骤 3: Paint the claws

Paint two large claws (chelae) extending from the front of the body. Each claw has a wider upper arm and a pincer at the end — paint a thick curved arm with two pointed finger shapes at the tip. Make the claws proportionally large — they should look powerful.

步骤 4: Add the legs

Paint four thin walking legs on each side of the body (eight legs total). They should be jointed — paint them as two segments that bend at an angle. Crabs walk sideways, so position the legs extending to the sides and slightly forward.

步骤 5: Add details and seal

Paint two small white eyes on tiny stalks at the front of the body. Add curved lines on the carapace with dark red to suggest texture. Add white highlights on the top of the claws for a shiny shell effect. Once dry, apply clear sealant.

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。
在开始画画之前，先用铅笔轻轻勾勒出设计。
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。
