Squaring a large quilt on a table
 

How would I square up a full-queen quilt on a dining room table? I'm not able to get on the floor to do it. Thanks for your help.

Well, if the table is big enough to fit 1/4 of the quilt at a time, I think I would run a bright coloured basting stitch thru the center from top to bottom and side to side. Then I would square up a quarter at a time, making sure that the measurements are constant for each quarter. If the table is not big enough for that, I tihink I'd wait until a larger space could be had.

i generally eye-ball it or use a large carpenter's square

"Squaring up" can have different meanings, depending on the stage of the quilt. Has your top already been quilted? Has it been bound? Is it out of square? What exactly are you trying to do?

If it is a top that has not been quilted, or a quilted top that has not yet yet been trimmed and bound, then you need only to measure to see whether the top is square, mark the lines to be cut, and then you can trim using a cutting board on your dining table. If your quilt has already been quilted and bound and you need to square it up by blocking it, then you really need to be able to stretch the whole quilt out, while it is damp, and secure the edges with pins to a carpet or cork board or something like that. I don't think that part can be done successfully unless the whole quilt is stretched out.
