Measure the thirteen stripes for your canvas using a ruler; mark off with a pencil.
After you've made your marks with a ruler, trace the lines out all the way across the canvas.
Mark out the union and star area that you are going to paint blue. I recommend five stripes tall and then 9 1/8" across.
Paint the red stripes using acrylic paint. Let dry. Erase any remaining pencil marks.
Paint the blue area with acrylic paint. Set the canvas aside to dry and then begin preparing your fabric.
Cut the fabric into strips a little over an inch, then cut into smaller squares a little over an inch. See the notes for estimated quantity.
Start with the blue area. Add Mod Podge to the canvas with a paintbrush. Place down a square of fabric and Mod Podge over the top.
Continue in this same method until the blue area is filled in, then work down the stripes. Use overlapping squares all the way down the canvas until covered. Let dry. Add a coat of Mod Podge to the canvas and let dry.
Paint 18 wood stars with white acrylic paint and let dry.
Glue the stars down to the canvas with craft glue. Let dry completely before hanging.
