It took me around an hour to mark and cut the 16 pieces.
About 20 mins to sew the pieces together.
A lot more swearing to sew the centre piece.
20 minutes to add the base piece.
10 minutes to stuff and 15 mins to hand sew the opening up. I used stuffing but if you're short of space you could use it to store a winter/summer duvet.
I up cycled a pair of curtains and an old table cloth for the project, unfortunately I cut the material the wrong way (there's a fancy way of saying this, Dias???) and as soon as I sat on it the seams started to rip and after much more swearing and hand sewing. I gave up and will try again tomorrow with a different cut.
And I'll reuse this material to make some patch work smaller cushions after re cutting it the other way.
