For throw pillows, I would recommend getting 5/8 yard fabric. My pillows were 18x18 and that gave me plenty of extra room.
For the body pillow I got 1 1/3 yards and that was a lot extra. Only used a yard probably. Measure the pillow on top of the fabric to see how far in to make the seam.
Have the fabric inside out fold it in a square so it is the right size but have the opening on the front facing side and overlap 4"
Sew a 1/2 inch seam the long ways where it will fold over, then sew the other sides together, making sure you are still overlapping. Make sure not to sew your pocket closed.
Flip it so it's not inside out And stuff your pillow in!
I love it you can't even tell I reupholstered them.
