I came across this idea a while ago, and was reminded from this disney props thread, and knew it'd be a simple thing to do that would make a great gift. I am going to be able to do it for under $35.
Here is the goal:
$32.10 = $17.55 plus $14.55 shipping for the jar. The proportions of the jar seem to change since it is an animation, but I've selected a jar that is 8" diameter and 11" tall, plus the handle.
$2.00 for a single rose
$0.10 worth of hot glue
$0.05 worth of fishing wire
I plan on hot glueing one end of the fishing line to the top inside of the jar, and tieing the other end in a loop. That way the rose will appear to float. When the real rose dies after a week or so, it will be easy to remove the rose, and add another into the loop without having to reglue and retie the rose.
Progress pics coming early next week, with the goal to have it done by next weekend for her birthday.
