It's always a challenge to keep fresh roses for an extended period. I've heard of adding a penny to the vase water, or mixing in a crushed Tylenol tablet in order to help preserve flowers. Barring these suggested solutions, I find that a photograph is the best way to keep flowers fresh for a looong time.
I've always wanted to have the Canucks hockey team in my own living room, and now thanks to Spencer Dubas' creativity I kind of do. He created patterns that you print out then cut and fold to form these three dimensional characters. Warning that if you like the Canucks and you like being crafty then you're going to get addicted to making these. If you've done origami or napkin folding in a restaurant in the past, that may give you a leg up on the manufacturing process involved here. Download the patterns to make them for your own fun, and keep checking back because it gets updated with more players pretty regularly.
