I have just used my sewing machine for the first time to make a cushion cover. Quite happy with the results actually.
I sewed the seams with the fabric inside out. I then turned it right way round and inserted cushion pad. When it was the right way round i could see some of the thread from the stitches showing theough on the seams. I think this is because the thread was a bit too loose. Is this a problem with the thread tension? Hope this makes sense.
