Directions:

1. Gather supplies: vintage postcard, ruler, scissors, pen or pencil, sewing machine. 
2. Make a template. Once you make the first set of triangles, hold onto it. You can use it to trace triangles for all future postcard mini banners. 
3. To make the template, mark 1/4 inch past the bottom of the postcard and draw a line. Starting at the bottom left corner, mark a dot on each 1 inch mark.
4. Then starting with the very bottom of the postcard, mark 1 1/2 inch vertical dots on the edges and draw a line across. 
5. Finally, begin measuring that line starting with 1/2 inch. Then mark a dot on the 1 1/2 inch , 2 1/2 inch, 3 1/2 inch 4 1/2 inch and finally 5 1/2 will take you to the outer right edge of the postcard. 
6. You are ready to use your ruler and connect the bottom dots to the top dots to create triangles. 
7. Cut out the triangles making sure to leave the bottom 1/4 inch attached. 
8. Use the template to trace the opposite side of the postcard with the triangles. 
9. Cut out. 
10. Finally, use your scissors to cut right down the center of the postcard. This will create a natural 1/4 inch border without needing to measure. 
11. You’ll now have 4 triangle lengths. Snip off any half triangles, leaving the 1/4 inch border. 
12. Use a bit of tape to attach the lengths together, overlapping with the little edges that were left from the half triangles that were snipped. 
13. Sew the long length of triangles together. But make sure you are sewing through the triangles and NOT through the 1/4 inch edge. You want to have space between the triangles so that they hang like a banner. 
14. Cut the 1/4 inch edge off. Now you have a mini banner!
