Cover the inside of your straw wreath with fresh rosemary cuttings, evergreen cuttings, leaves, goldenrod, artemisias, baby's breath or other durable plant. Snip the stem of the plant and attach the stem to the wreath with a floral pin. Place your next stem overlapping the first working your way around the circle. Continue covering the straw in the same manner starting with the inside circle, then the face and then the outer circle.
Cut fresh flowers and immediately place them in a bucket with flower extender. You can mix your own floral extender by simply adding 2 tablespoons of lemon juice, 1 tablespoon of sugar and 2 drops of bleach to 1 gallon of water.
Cut flower stems under water to the length you need. This prevents the stem from filling with air bubbles. Fill a water-pick with extender water and clip it over the stem of the flower.
Insert the flower into the straw wreath. A straw wreath is made of long straw strips that are gathered into a bundle and tied every few inches with wire. This makes straw easy to open to slide picks and staples into the straw. Attach several similar flowers in a single large cluster or make a ring of flowers that circles the wreath.
Add a door hanger, ribbons and other finishing touches and your wreath is complete.
