I want to sew some box-cushions with foam filling, for the children to go out for a picknick on these last days of summer. This is a really easy tutorial to sew. I made it on the BERNINA 710, this machine is quite similar, this machine is similar to others in the 700 series.
How to find out how much fabric I need:
I want my cushions to be 35 x 35 cm. I cut the foam pieces 34,5 x 34,5 cm, to have a little extra space for the seams and to prevent from deformation.
As the filling is 1 cm, I need to count this extra cm in the surface of the fabric. 35 cm + 1 cm for the foam, + 2 x 1 cm seam allowance, makes 38 cm. I need this for both sides. To work easily, I cut it on fabric fold, that saves a 2 cm fabric. The fabric I need, should be 38 cm x 74 cm and I took a water repellent fabric.
- For each cushion of 35 x 35 cm (and 1 cm thick): 38 x 74 cm fabric
- Mettler Seralon sewing thread,
- A sharp needle,
- 1 cm foam (34,5 x 34,5 cm
- Standard paper
- Optional: 22 cm tape for a handle.
I fold the fabric over, right sides together and pin it on the seam allowance. Of course I take the pins away before sewing the seams. Only sew over pins when you put them cross the seam.
I sew both side seams and part of the side opposite to the fold with a larger stitch (I took stitch length 3).
Now, I need to cut away the corners.
I fold the corners over, check if seam or foldline match.
I draw a 1 cm line across the corner.
This short line needs to be sewn, to give a volume to the cushion. With the open embroideryfoot 20 it is possible to have a clear view on my work. I stitch over a piece of paper to prevent the stitches from constricting my fabric.
When the 4 corners are ready, I can turn the cushion. Can you see the volume?
Would you like a handle? Put it in before sewing the opening..
Do you think it is difficult to put it in? You could as well sew it in a sideseam (place the ribbon on the inside, between the right sides of the cushion, while pinning).
