Easy Removeable Cushion Cover

I found this sponge for cushion on the side of the street... People throw away good things these days. I am in the need of new cushion for our plasticky chair... so I'd say it's perfect.

This is the tricky part. The measurement. Remember, better measure big than too small. Start to measure like photo below :

Measure from point A to B. Add 3cm seam allowance, that would be the measurement of the LONG side. Do the same for the WIDE side.

Now you got the measurement of LONG side and WIDE side, seam allowance included. Cut your fabric, based on your measurement. Sew all the way,... don't forget to leave one side open for the opening. At this point, try it ...on your cushion to check if it's fit nicely or need adjusment. Try it with wrong side out... that way it's easy to pin or mark the excess fabric, if that's the case.
After everything fit... you can double the stitch for reinforcement.

Now measure the HEIGH individually, in my case is 8cm.

Find both corner of your cushion cover. Folded like in the photo below...

Mark 8 cm, and stitch there... from point A to B. Cut out the excess corner..

And .... you are finish!!

This is the opening of my cushion cover, closed with ribbon.

Fit nicely! Ready to sit on...

Congratulation,... you have just spicen up your old cushion. And when it gets dirty, easy remove the cover out and put it in the washing.
