no, I don't do this myself, but here are some ideas.
Put a pink bow on it for Valentines Day; even beter if you could find ribbon that has hearts on it...
Then for St. Pat's, use a green bow, foam shamrocks.
Easter--plastic eggs, pastel bow, maybe a small toy bunny wired to the wreath.
Memorial Day/4th of July--flags, red/white/blue ribbon.
Halloween--orange and black bow/ribbons, foam pumpkins, ghosts, and black cats, small plastic spiders
Fall/Thanksgiving--colorful leaves, nuts, pine cones, acorns, seed pods (milkweed, sycamore), gold, orange, burgundy or brown ribbons for bow; you could spray-paint the seed pods or cones if you want; "leaf garland"
Even if you find some beads or necklaces at a garage sale or thrift store, in the colors you want, they can be wrapped around or woven through the wreath; or look for garland in whatever colors
Walk through your fabric/craft store for ideas too. Have fun!
