I bought two of these chairs.
This week I thought they had a lot of potential but they look old.
So I searched on Youtube and foundA Buterfly Housestutorial on doing a chair makeover.

Directions:
Start by taking apart any parts of the chair that can be taken apart.
For this chair, that was just the seat, but some hairs came off the back as well.
In the next step, you should spray paint the wicker on the chair.

Take care not to spray too close to the chair.
Wrap the fabric around the chairs seat and staple it in place to make it look like new again.
It wont get in the way and wont show through the thick duct canvas.

Remove all the staples with care.
When the chair is dry, cover the back with the back.
It will be hard to secure new staples if you leave old fabric on.
You need the back fabric to cut a template.
When you cut new fabric, use the old fabric as a guide to confirm it fits.
Line it up, adding about half an inch to each line as you go.
This will give you a little extra fabric to work with.
Then, use your fabric scissors to cut the fabric into the shape that you want it.
Its time to sew the fabric to the chair after you cut it out.
Cut and sew the fabric together in both places.
Its time to work on the pipes!
With a sewing machine, you could cover up the piping.
To do that, you first glue one side of the piping to the fabric.
Then, you wrap the fabric around the piping and pin it to the fabric.
