How To Make Cushion Covers! Super Easy!

My friend bought a camper that needed some cushions quickly recovered and here's what I did! These are like a fitted sheet, easy to make, I did 4 in an afternoon, washable too!
This will work for ANY cushion! Whatever the depth of cushion add same amount to the underside for a perfect fit.

The formula I used was :
Length + depth + depth + depth + depth = fabric length
Width + depth + depth + depth + depth = fabric width

The depth will be your cushion depth. Mine was 4". You will have this on each end and each top & bottom.
Cushion example: length= 50" with a 4" deep foam.
50 + 4+4 (one end) 4+4 (other end) =66" long fabric. Do the same for the width and you have the fabric laid out. Lay cushion on fabric and measure 8" in all directions to center cushion. Proceed as directed in video.
