screenprinting with embroidery hoops and netting

[xnikki118x.livejournal.com]

Hi crafters! I've read on here about people screenprinting using an embroidery hoop and some kind of netting to make the screens.

Where would someone buy embroidery hoops like that? Do they only come in circles or are they available in other shapes as well? And what kind of netting should be used? Do you use like tulle from a fabric store?

I was talking about it with a friend, and now she wants to get me the supplies for Christmas, but neither of us have any idea where to go or what kind of netting to get.

Thanks in advance for any help!
