Approximate Time: Depending on size, about an hour
Cut plastic canvas to desired size. Plan out your design and go for it. I discovered that if you do the edges and a center design, leaving the rest "open," it seems to work better.
Stitch design, wrap stitch the outer edge. Using the tie straps, attach to the antenna and there you go!
I am now experimenting with beads in the center to look more feminine and to jazz them up a bit.

They don't damage the paint. I change them with the holidays, orange for fall, red for Christmas and Valentine's Day and green for St Patty's Day. Just throw them away when they are looking tacky or it is time to change. An added benefit when meeting someone in a public place, just say I'll have the red ribbon attached to the top of my van.

What do you tie the bag to on top of your car?
Radio antenna is the usual site. If your car doesn't have one, you could use the roof rack, or you could get one of those flags that fit in the window that show your favorite sports team, and then add something to that. It isn't as high as an antenna, but it will help.
