The selection is very limited, but there is fabric out there that is exactly 108 inches wide. It is specially made so that you don't need to make any seams for quilt backing. Of course, you will lose about 1/2 inch or so on the selvedge sides, but you could buy another complimenting fabric to make a nice binding, which would also add to the beauty of the edge IMHO.

If you do choose a fabric that you need to make seams with, I don't really see that as an issue. You might buy a complimentary fabric and made a binding (you wouldn't need to make it on the bias, as you are making straight seams) and sew one edge down, then fold over and hand sew a hidden seam and nobody will be the wiser.

Is it possible to divide your seams up as you would for a bedspread? What I mean by this is to make the part that covers the surface of your table seamless and divide the rest of your width into 2 side pieces that would hang down on the sides of the table. Just how wide is your table on the surface? I'm not sure I understand why you would need to seam it lengthwise.

You'll have 2 seams width wise and none length wise. You'll need 11 yards of fabric, 5 1/2 yds each side (well if it's a solid color that is, a print would have to be matched, so more fabric). Use one full piece for the center, then cut the other piece in half and sew to each side of the center piece.

Thank you all for your help! I'm not sure what I was thinking about the length-wise seam... I thought about doing the bedspread-style where it is perfectly tailored, but the table is kind of an in-between a rectangle and an oval, so I would have to perfectly pattern it out. Given my sewing skills, I don't think that would happen. I have seen some beautiful ones online that do that though-- with pleats in the corner it's gorgeous!

I think I will try to method you suggest, shadylady. I think my best bet is to find a fabric with a pattern that will hide the seam more than a solid would. I do still worry about a seam running right around the perimeter when you look from far away. Probably worth a shot though!

OK, you didn't say it was oval :) So you'll need to make a template of the top, which you'll trace to the back of the fabric and add 1/2" SA. Then you'll sew the drop onto the top, all around, put it on the table, wrong side up, and measure all around, 1/2" from the floor, making small dots, then connect the dots, adding your hem size. Don't know what kind of hem you were planning on making.

Not sure what size your table is, so not sure if cutting one width in half will leave you with enough drop or not. You can add a micro cord in the seam around the table for a nice look. You'll also end up with a seam or two around the drop part.

If you're going to eat on the tablecloth, you'll need to forego the pleats in the corners, or no one will be able to put their legs under the table because of the tightness. :)
