First, you will need to gather some supplies. You may have many of these items. These items are also available at your local craft store. I also provide links to the supplies in the post.
Use the pinking shears to cut the white fabric into 12 rectangles that are 5" x 3". The shears create a zig zag pattern on the fabric and prevent the edges from fraying.
Then use the pinking shears to cut your blue pattered fabric into 12 rectangles that are 2" x 1 ". As you can see, I used two types of blue patterned fabric.
Use the hot glue gun to attach the blue rectangles to the flag. Trim your silver piper cleaners into 1/4" pieces and attach them to the blue fabric. These silver pieces represent the "stars".
