Ok, after all the preparation, it is time to start the upholstry. I first took the small block for the test, because it is cheaper to buy a new small piece of cloth when it goes wrong instead of the C-shape piece.Glew the foam
- use appropriate glue for the foam (I used Bison Tix). Let it dry for the required time (15 / 20 minutes) before mounting it together!
- start pushing the edges together, lifting the center piece. Work your way from the edges in.
The edges will look chamfered, something like this: \_/
When the upholstery is put on, it will get it back into the shape, creating straight edges.Mounting the top part
- measure the rough shape and keep about 10 cm extra to pull it into shape.
- use the staple gun (in an angle, see Tips) to get the first stretchingin place. Start at the corners and make sure to see that the curving is ok. Continue with the sides.
- check if everything is straight and if tension is high enough. You can check this by placing your hands on the side and move to the middle. If the upholstry curls up, there is not enough tension.
If the edges are not even, there is probably too much tension.
- because of the non-stretch of the colth I used, no evenly tensioned without wrinkles corners were possible, so I decided to use folded corners (see pictures)
- finish the top by stapling it. Use one staple length between staples to get even tension.
- cut the remainder part by marking it evenly. (I used a piece of wood again with a mark on it and a pen to trace the line whole around.Continue with the sides
- I used one length of cloth for the sides, getting one sewing edge at one corner
- mount the white cloth inside out and use a strip of cardboard which will create the sharp edges.
- put the inner padding on, some extra on the edges
- fold down the cloth and staple it on the bottom. Use the same technique as described above (using angled staples). Finish the bottom part first for the three edges that can be fixed. Leave the sewing edge open.
- fold the last corner in shape and use pins to keep it in shape. Staple it on the bottom with temporary staples. Check if the corners are not too bulky, else fold it in further and remove cloth that is not needed / out of sight (!
be carefull cutting)
- start the sewing at the top by creating a knot at the end, pull it through both corner-ends with the special curved needle and get it back through the knot. If you want to make shure it stays put, sew it fixed to the red top cloth.
From there, get from the back from one side to the other side and push the needle through, bending it back so it pops out 4 to 5 mm in the other side. Something like this:

Continue your way down with even stiches and finisch at the end.
- finish the bottom by stapling it fixed and cutting the remaining cloth around 5 mm from the line of staples !Tips / Remarks
- Use the staple gun in an angle for the 'tagging'. It is easy to remove the nails when you make mistakes, as only one 'leg' of the staple is in the wood.
- Stretch all corners and sides evenly. Use a lot of views to see if the lines (curves) are even and straight. View it from eye-height, turn it around, put it on the floor and do the same!
