New cushions on the sofa

In fact the inserts are the old ones, but the covers are new.
I didn't take photos for a tutorial but they are very quick to make. I bought 1 metre and a half (60 inches) of this synthetic furry fabric, and managed to make 4 cushion covers. Each one is roughly 40 cm (16 inches) square finished.

I cut my fabric 42 cm(16 3/4") large by 95 cm(37 1/2") long. It doesn't have to be so precise on the length.
Next you need to sew a double return to make a hem on the 2 short ends.

Now put your pad or insert in the middle, and overlap the ends of your cushion cover, right sides outside. You can decide where you want the overlap to be. Pin the fabrics together. There is no need to measure with this method, it will fit.
Take the insert out through one of the open sides, turn the cover outside in and pin the open sides closed. You need to sew along each of the 2 sides, and then zigzag the edges if necessary (it was for my furry fabric).

Turn it right side out and you have finished. Bravo.
There was no need to put a zip (go to a store and buy one) or to make button holes and hand sew the buttons. It was also very fast.

I was amazed at the mess this fabric made on my floor. Lots of little threads went everywhere.

And I will have to cover more cushions as I realised that the fabric on some of them was getting worn out. It's a shame as I liked them, but then it gives me the opportunity to make something new.
