Here is my first attempt at making a wreath.
I used my trusty glue gun, a $5 wreath from Michael's, two packs of small ornaments, a sprig of sugared berries, and an old 'Happy Holidays' ornament from last year.
Do a trial run and place the decorations around the wreath. This way you get an idea of where you want to put things, prior to gluing. Try to space things out evenly and don't repeat exact patterns/colors. Make each little cluster is a little different. Use hot glue to set the decorations once you have it perfect.
Oh, and don't get hot glue on your finger and touch your eyebrow. Just a word to the wise.
