They came with C clamps, and some came with little suitcases that turned into table top tables.
What I'd really like
is to have Rodney make me a base...but I'm still thinking on ideas for stability.
a tray with a heavy duty suction cup on the machine also comes to mind. I've collected images of a lot of ideas but can't share them here as they would be deleted as not mine.
I have my Sewhandy project lined out in my mind also. So if the work is successful I'll start a thread then.
