Have put together a spreadsheet from several vendors who sell cuben fabric and related supplies with prices for the DIY crowd.
Most vendors are selling the cuben by the yard but some sell by the 1/2 yard or foot in which case I worked out the by the yard price for comparison.
If I missed any vendors, feel free to add them.
Prices do change so be sure to check the vendors for the latest prices.

Yama Mt Gear does make a stuff bag kit for $ 30 that includes everything you need to make several cuben stuff sacks. Easy and fun if you wanted to play around with cuben and find out how to work with it before you tackle a big project like a tarp and find out its more than you can handle.
