We've had our dining set in storage the last 4 years..
amounts depend on your table
tablecloth vinyl/ oil cloth (I used 2 yards for mine)
double-wide bias tape (I used 2 (3yd) packages)
Here's a video from the owl tote that shows the same idea on a corner
Continue around tablecloth, opening and sewing the seams in the strip flat when you come to them.
4. Finish Sides
When you come around to the end, stop sewing a few inches from where you began.
At this point you should have 2 ends of your long strip to work with.
Lay the main tablecloth flat and meet the 2 side ends together.
Pin them where the final seam should be.
Pin the 2 sides of the strip together, and sew them together at your pin mark.
Trim off any extra strip you may have, and sew the last seam flat to the tablecloth.
5. Add Bias Tape Trim
Rather than fold and hem, I chose to add bias tape for a quick, easy way to add a solid color around the bottom of the tablecloth.
I used extra wide, double fold bias tape.
Obviously these instructions are specifically for square or rectangular tables, but you could made a round or oval tablecloth the same way, just lay your fabric on the table and trim the correct shape, leaving the 3/4 to 1" extra along all the edges.
