Flowers

• Decorate your church aisle by hanging orange and brown flower arrangements from the pews. Use traditional wedding flowers such as roses and calla lilies. Both naturally bloom with orange or brown petals. Gerbera daisies also come in orange. Or use food coloring to dye any white flower you like orange or brown. Use fresh or fake silk flowers for your arrangements.
  
  

Ribbons

• Bring your wedding colors to your church pews with orange and brown ribbons. For a large, loopy bow, use wired ribbon. Make or buy pull bows with unwired ribbon for aisle decorations. Or tie the ribbon into bowties to hang on the end of the pews.
  
  

Pumpkins and Acorns

• Flowers aren't the only natural decoration you can use. Line the church aisle with orange pumpkins. You can leave the pumpkins untouched or turn them into lanterns by craving pretty patterns into them and putting a candle inside. Add brown by hanging bunches of acorns from the pews.
  
  

Colored Tulle

• White tulle is often used as a wedding dress material and decoration material. While tulle is usually white, you can buy frolm fabric stores and online retailers in an array of colors, including orange and brown. Drape it between the church benches or bunch it together to form arrangements.
  
  

Aisle Runner

• Much like a special occasion red carpet, the aisle runner is a piece of fabric that you lay down on the church aisle. Choose a brown or orange aisle runner, then have it monogrammed with your and your fiance's names, in the opposite color. Use a brown runner then have your flower girl toss orange flower petals down on it..
