Start with your wreath form. You can use any size you like. The one shown uses a 10-inch form.
Grab your marshmallows and toothpicks. For this size wreath, I needed almost 3 standard-size bags of marshmallows and I used standard double-sided toothpicks.
Start with the outer edge of the wreath, press a toothpick into the wreath form, and then add a marshmallow to the toothpick. The toothpick should be in the wreath far enough that it doesn't stick out the opposite end of your marshmallow.
Continue working all the way around the outer edge until it is full. I like to place the marshmallows pretty close together for a filled-in look. You can add the marshmallows in any direction you'd like. For my wreath, I varied the direction for a more whimsical look. In regards to the wreath my mom made, she was pretty consistent with how she placed the marshmallows so it looks a bit tidier.
With the outer ring of the wreath complete, repeat the same process in the inner ring.
Once you have the outside and inside of the wreath complete, just start filling in. I recommend filling in one area and working your way around the wreath until you end up back where you started.
Once the wreath is full and filled, add on a ribbon and a bow and hang that beauty up.
