I have thought and tried this method for the first time. It can have many variations in color, content and size.
Inside the postage stamp you can paint/print the content using any method of your choice. I'm creating a stencil for the inner content also.
1. An image file (jpg/gif/.. on your laptop/tablet) that you want to appear inside your postage stamp. Choose simpler images preferably outlines only.
2. Plain paper, pencil
4. Xacto knife
5. Fabric colors - White, Green and Blue
6. A T-Shirt on which you want to print the postage stamp
Step 1: Select Image
On a paper draw 3 rectangles one inside another as shown in the second image.
Step 2: Create the Outer Edge of Postage Stamp
Note - You can also draw semicircles only on two sides. In that case find the mid point of the rectangle and fold it into half. Now cut along the semicircles with scissors. This way two side will cut in a single go.
After cutting the semicircles the stencil will look like the third image.
Step 3: Trace the Image
Trace the image on paper at the desired position. Cut the figure with Xacto knife
Step 4: Fill Color in Outer Area of Stamp
Step 5: Fill Inner Rectangle
Step 6: Fill Color in Figure
You can write some text as I have written "This Is It !!".
