Q&A for How to Make a Tablecloth

Yes, as long as the diameter of the table is smaller than the width of the rectangle.

Add panels of the same or contrasting color/pattern on each side that needs more length.

I cut off the selvage before hemming a tablecloth. The selvage is woven tighter than the rest of the fabric and will shrink at a different rate, potentially creating puckers along the edge of the tablecloth unless removed!

It will probably be a very small tablecloth and difficult to work with, but it can be done. It all depends on the size of table you're trying to cover.

You should choose a fabric that is at least 58"-60" wide for a tablecloth. Otherwise, think about adding a border all the way around. Seaming really isn't a professional option.

There are plastic or PVC liners, which are good for wood tables. They protect tables from water and temperature damage. Rubber liners are about the same. You could also get felt, but it's trickier to keep in place.

Laying the tablecloth out and cutting around its perimeter will help, but hemming it may be easier. Fold the end up and sew it to hide some of the excess length.

Linen or cotton are the traditional choices since they are both soft and durable. They absorb liquids well, too. You can also use polyester or vinyl for a stain-resistant cloth. Some people even make specialty products out of fabrics like silk.

For a well-cut tablecloth, you usually won't have anything holding it in place except a liner underneath it. Many tablecloths have mitered corners that fit securely over the table's corners to help hold it down too if your table is rectangular. You could also put a bowl, flowers, or something else on top to pin it.
