Clay to make a mini retro luggage model. Of course, if you don’t have clay, you can use plasticine or polymer clay. They are all similar materials. The only difference is the hardness of the material and whether it needs to be baked.
The color of this luggage decoration can be DIYed in any way, and you don’t have to follow the tutorial exactly. For the specific production method, please look at the detailed illustration below. It should be no problem without reading the text (the font is too small, sorry~).
