I originally made these four years ago for another graduation party and am finally getting around to writing down what I did. Since they were completely made using recycled jeans the cost was free. With all the expenses of throwing a party, not having to buy tablecloths is a win-win.
You will need lots and lots of old blue jeans. Since I have grown boys and I seem to save everything, I have a steady stash of jeans. My friends and extended family are also great sources for keeping me well stocked.
Each block was a 14-inch jean square. I cut the legs off of the jeans and opened up each leg along the flat-fell seam. Actually, I completely cut off the seams and saved them for other projects.
Most adult jean legs yielded two squares (four per adult jeans). If there was a hole in a knee, I was only able to get one square from the leg. A square can be pieced if needed.
I flipped the rows back over with the front facing up and top stitched along the seam, catching the raw seams on the back in the stitching. The top stitching makes the tablecloth lay very flat and prevents seams coming apart from fraying.
Each row was stitched together and more top stitching was done over the new seams.
Now that the last graduation has past, I think the tablecloths will make great picnic blankets.
