I have never done it meeself, but as it is a natural fiber, I don't see it as being a problem...the indications for acrylic fabric ink is that they are suitable for natural fibers....but if any certain fabric is too thin or pourous, there will be bleed-through.....

Well, screen printing has never been a very green process, the emulsions, inks and solvents required are substantial. Even for a water-based process you need to collect and filter your wastewater, which is no small task.

I would encourage you to investigate the use of natural or remanufatured dyes, especially those made from locally available natural materials. Once you have identified your preferred ink and design requirements, you can decide on the application method.

The processing of your fabric will have some bearing on it's ability to absorb ink, but unless you're already habituated to working with cotton, I think your learning curve will be about the same, whatever the fabric you start out with.
