Cut out the photos - use the flat wooden rounds (mine was about 3" in diameter) as a guide. Make sure your photos are centered on the ornament.
Adhere the photo onto the circle round with glue and smooth. Let dry for 20 minutes.
Apply a layer of glue on top to secure your photo and to further protect it from elements (this is specially important if you just printed your photos using a home printer).
Cut out your leaves on green cardstock paper - you can definitely cut this by hand, or use a die-cutter for convenience. You can trace the template provided! Alternatively, you can purchase leaf embellishments at the craft store or online.
Burnish your leaves to give them a more natural feel, using the ball tip tool. I used the tip of my calligraphy pen to burnish my leaves. You also want to burnish it on top of something smooth, such as fun foam.
Adhere the leaves around the photo using the glue.
Adhere a second layer of leaves going the opposite direction of the first layer to add more dimension and a natural feel to your wreath.
Attach a grosgrain ribbon on the back of the ornament to hang.
Notes
If you only have an inkjet printer, use hairspray or acrylic sealer on both sides of the printed photo so the Mod Podge doesn't bleed.
To give the ornament a more finished back, add a felt circle with craft glue.
