To do a paper swap, just means that each participant sends a sheet of paper to each of the other participants. There were ten people participating, so I sent out paper to the other nine people. And I received nine in return (actually, eight marbled papers and one piece of marbled fabric). Marbled treats in the mail! Each of the participants have kindly given me permission to share photos of their marbling here on my blog.
Visit Barb Skoog's blog to see the nine papers that she received - all different than the ones I just showed you, and all equally amazing!
