I love the HSN craft shows and think they do an great job. They certainly seem to have cornered the market on the best crafters. Their shipping deals are incredible! Yesterday, you paid no more than $5 in shipping all day no matter who many craft items you purchased.
Not sure who QVC could find in order to provide such shows. And I'm not sure QVC would be prepared to offer those awesome shipping deals. HSN gets plenty of business from me on their craft days, especially.
Don't get me wrong....I loved when QVC used to offer craft shows. I was working at that time, and I would schedule vacation days to be home for the QVC craft days. That ship has sailed for QVC, though I believe they did try a show or two a year or so ago.
