Was just at Aircraft Spruce on Friday... they have a surplus of manpower in the warehouse there... so if they need three or four guys to roll one of the sheets up it's not a problem.
But for one person like you and me, it can get to be a lot harder and more embarrassing- "Like a monkey trying to **** a football" as one of my favorite flight instructors said.
What you can do is move the sheet to where the far edge of it is against a wall, or a heavy object. Put it on the ground with a piece of foam, fabric, carpet, cardboard, etc. under it. This makes it so it can't slide around and scratch the aluminum, or remove your Alclad layer..
Then you can lift up the near end and roll the sheet by yourself, pressing against the wall or whatever to keep control of it..
But
before you start rolling the sheet, take a piece of string or twine and make a quick loop in one end, then run the free end through the loop, making a poor man's noose. Have this noose ready next to the wall or floor stop object. When it's set up in advance like that, you can slip your noose over the roll, pull it tight, and tie it off.
Then you can stand the roll up, move it around, and contact Red at the Possum Lodge Aerospace Engineering company for additional securing methods
If you want to make points for cleverness, you can tie another loop in the string and tape the string to the roll, and use that loop as a lifting handle.
