These wreaths were made from wisteria vines that were running rampant in my backyard. They are the easiest to weave when they are fresh (you can see this first wreath is still green, I just made it yesterday. It's pretty easy to do, just weave in a circular pattern going over and under, and tucking the new pieces into the existing pattern. The hardest part is getting the consistency, and making sure it actually looks circular. Mine are a bit lumpy but nothing I can't fix from bending and pressing into shape.
Trish's wreath used wooden numbers that she painted white with acrylic paint and blue silk hydrangea flowers. She decided on numbers for the number of her house address rather than the letter "L" because she didn't like any of the "L"'s the craft store. Way to improvise, Trish! 
The red wreath was made almost entirely from decorations from the Dollar Tree, which in my opinion is the best "first stop" on your way to shop for craft supplies. Sometimes their silk flowers look good, sometimes they don't but it's always worth a shot in my opinion!
The second blue wreath uses cut up blue burlap strips purchased from jomar fabrics, thick twine as an accent, and the leaves are from either the Dollar Store or Michaels. All you need are scissors, wire clippers, and a hot glue gun! Grape vine wreaths are between $3-$10 at AC Moore and Michaels.
Julie made her wreath with strips of plain burlap, decorative yarn and ribbon, and silk flowers. She still had fabric from her wedding and I still had some from mine, so we put it to use.
