Why kill flowers when you can just make one, in the case of this origami boutonniere.

The bridal party got origami necklaces, origami place cards, the centerpieces and even the bride's bouquet were made from origami flowers!

This Etsy seller took the "trash the dress" concept to a whole new, awesomely crafty level. From the Etsy listing:

Handspun Art Yarn from my wedding dress – UpcycleBB Contest Entry – take something no longer useful and upcycle it to a higher purpose…One (1) 16 yr. old size 8 country tulle style wedding dress. Cut into long thin strips and scraps using sewing shears. Handspun into singles on a foot operated spinning wheel. Plyed on a drop spindle. No other material used. Transformed into 181 yards of useable art yarn.

(Thanks for the heads up, Marie!)
