As I had no vase, I decided to use (of all things) a beer bottle. I made sure it didn't have any writing up on the neck. I measured a peice of pretty scrapbook paper and glued on the lacy edges of read paper. I then used Mod Podge to glue the paper onto the glass. (I can't tell you how much I love mod podge-- I've used it a gazzillion times since we got it). Then I tied some ribbons on.
To dry the roses, I simply took a live rose, tied a string to the end, and taped the string to my closet wall (so the rose hung upside down).
If you use flowers that aren't already mostly dead, they turn out much prettier than the ones pictured here. Also, if you are not having to show the house, you can tape the flowers so that they hang from your ceiling-- I think thats pretty. :) Oh, be sure to open up the middle petals, so that you don't wind up with mold in the flower. And don't set them behind your shelf absentmindedly. You forget about them and they get dusty.
I made this quite awhile ago, and it was so nice to have flowers inside during the winter. And nice to have flowers inside that aren't weeds. We are in a sad way as far as nice, pickable flowers go. :)
