I want to DIY a Kanoe baby hammock, any body have one to compare to?

I can't afford the $290 sticker shock http://www.kanoe.us/3.html I think I will try to DIY one, my question is with support bars on the fabric section. I am wondering if the straight bar across the upper sides is the only one or if there is a curved one on the bottom portion too??? I already have twill that was a no go from another project it looks like I will need dowel rods for the sides and spreader bar eye lag bolt and spring and carribeaner as well........ Any body have ideas on how to DIY this project or have one to compare my idea to?
