步驟 1: Paint the dark background and plan the design

Wash and dry your rock. Paint the entire surface black or very dark green. Let dry. Print a Celtic knot reference image (a simple triquetra or interlace knot). Transfer the design by sketching it with pencil directly on the dark painted rock. Take your time — Celtic knots require precise planning.

步驟 2: Paint the knot ribbon strands

Using forest green paint and your fine brush, carefully paint the ribbon strands of the Celtic knot following your pencil lines. Celtic knots consist of continuous interlacing ribbons that loop over and under each other. Keep each ribbon about the same width throughout.

步驟 3: Create the over-under weaving effect

The most important part of a Celtic knot is showing which strand passes over and which passes under. At each crossing point, one strand is continuous and one is interrupted. Paint the "over" strand as a solid line, and leave a small gap in the "under" strand where they cross. Use slightly darker green in the gap areas.

步驟 4: Add highlights and shading to the ribbons

Using light green paint, add a highlight line along the center or upper edge of each ribbon strand. This shading suggests that the ribbons are three-dimensional bands, not flat lines. Use darker green for the shaded edges. Gold outlines along the ribbon edges add richness.

步驟 5: Add gold outlines and seal

Using gold paint and your finest brush, carefully outline the outer edges of all ribbon strands. This gold border makes the Celtic knot look like illuminated manuscript artwork. Apply clear sealant to protect your intricate Celtic design.

步驟 6: 添加 RoxGeo 代碼

在你的石頭底部或背面寫上 ROXGEO.COM，接著加上斜線和你石頭的唯一代碼（例如 ROXGEO.COM/ABC123）。這樣尋找者就能直接訪問你石頭的個人資料頁面並記錄他們的發現。如果石頭太小無法寫下完整地址，可以寫 #ROX，接著是沒有空格的代碼（例如 #ROXABC123）——這樣簡短，容易在 Google 上搜尋，並直接引導到你石頭的旅程頁面。使用細尖的永久性標記筆或壓克力畫筆，並用透明清漆封住，這樣代碼在雨水、陽光和冒險中都能保持可讀。

有用的提示

在開始畫畫之前，先用鉛筆輕輕勾勒出設計。
在添加下一層之前，讓每一層完全乾燥。
選擇一塊形狀適合你設計主題的石頭。
用透明密封噴霧保護石頭，使其在戶外也能持久。
對於底部的 RoxGeo 代碼，使用防水永久性標記筆（如 Sharpie）或壓克力畫筆。在代碼上塗抹 2-3 層透明密封劑——這樣可以在雨水、陽光和處理中保持可讀數月。
在你的石頭上寫上 #ROXCODE（例如 #ROXABC123）可以讓人通過 Google 搜尋輕鬆找到。我們會主動優化這個標籤，因此任何搜尋它的人都能快速找到你石頭的個人資料頁面。
完整地址 ROXGEO.COM/CODE 會直接帶尋找者到你石頭的卡片，讓他們可以查看完整的旅行歷史、之前的尋找者和每個停留點的照片。
