Does anybody know how a way for me to go about making this?

I found this Manto 166 Utility Tripod Apron online at a href="http://www.markertek.com" rel="nofollow"http://www.markertek.com/a and I would really like one but it is way too expensive. Does anyone know a cheap way for me to make something similar for one of my tripods? Keep in mind I have no sewing experience....
