The fabric was £5 a Meter and the sofa only requires 5 Meters (from a 147cm roll).
Step 1: Designs
MEASUREMENTS ARE APPROXIMATE!
Don't take my word on the measurements! Much of this design was cut to the size of each piece as I went along so I didn't carefully measure anything.
Step 2: Gather Materials!
-Sewing Machine (you could probably hand sew the whole thing if you don't have one).
-Fabric! 147cm Width X 5 Meters (I used a Polycotton Drill)
Step 3: Disassemble and Re-stretch Old Fabric
The whole thing is held together with wing nuts and comes apart in minutes. Remove the threaded bolts from the arm piece and put to one side. This is a good time to perform any other repairs that the sofa might have already needed... Loose staples, wobbly joints etc.
Re-stretch Old Fabric.
This step is important to avoid the old fabric gathering underneath your new fabric. As you can see in image 003 I removed the staples from the end of the seating section. My girlfriend pulled the fabric tight whilst I stapled it back down. Don't pull it too tight though because it's easy to accidentally compress the foam padding unevenly.
Step 4: The Seat - Top, Front & Rear
Don't forget to check you fabric is the correct side up.
I found the easiest way to achieve a nice flat and evenly stretched finish was to lay the seat upside-down on the fabric. Next I attached the fabric bottom front side of the seat using the staple gun. I then rolled the seat forwards until I could access the rear of the seat (Image 003). I then stapled the fabric before cutting it from the rest of the roll.
Step 5: The Seat - Sides
Step 6: The Back - Front & Rear
In order to hide the stitching we will need to turn the cover for the back inside out after sewing. This means that you must follow these steps with the fabric facing outside in. In other words the side that you want people to sit on will be facing inwards in this step. If you have a cat then ask him to stand nearby and remind you about this.
Begin as in the previous step by stapling one edge and rolling the sofa back over the fabric. This time only use a few staple on each section as we will be removing this in order to sew the sides on.
Overlap the fabric on the edge of the sofa to allow room for stitching the sides on. Cut the fabric on the other side to overlap by the same amount. The off cut will be large enough to make the side pieces from.
During the cutting stages you may find it helpful to weigh the edges of the fabric down with a spare cat. This will stop it blowing away. Do not let the cat steal the fabric.
Step 7: The Back - Side Panels
Stand the back section on it's side. Pin the side panel in place, it may also help to mark a sewing line using chalk or crayon. There is a slightly awkward lip that curves over the top of the sofa seat. You may have to hand sew this section in a later stage although I managed to carefully staple it in place.
My girlfriend was on sewing machine duty and suggested that we sew one side panel first in order to check our measurements. This turned out to be a useful idea as it allowed us to ensure the opposite side panel was attached in a way that nicely stretched the fabric across the sofa back. Once the side panels have been sewed you can turn this piece inside out and slip it back over the sofa. The inside-out seem will look very neat (Image 005).
Step 8: The Back - Details
Once again be cautious of over stretching the fabric.
On the rear side of the back section I stapled the overlap (that had initially been created for sewing the side panels) to the side of the back section. (Image 003)
Step 9: The Armrests
Don't forget to check which way the fabric is facing.
The excess was simply stapled underneath.
You may wish to consider which way the 'tab' fold faces. You will probably want the seems to match on each side of the sofa so don't forget to make the second armrest as a mirrored version of the first. Also remember that the seem will reverse sides after sewing because you will be turning it inside out.
Step 10: Cutting Bolt Holes
You will need to repeat these steps on each piece of the Sofa. There are 4 bolt holes on each arm rest, 6 on the backrest and 4 on the seat.
Replace the bolts, wing nuts, feet and carefully reassemble your Reupholstered Klobo Sofa!
Step 11: Finished!
Very effective, very cheap, very individual and pretty comfy for a sofa that costs less than £100!
I haven't included it in the instructable but we also made a few arm protectors from the remnants of the fabric. You can see them in the first image of this instructable.
