You know it's time to stop sewing and go to bed when:

You wake up at your sewing table with the pattern imprinted on your forehead.

Your fingers have more holes in them than your pin cushions.

You have put your button holes where your zipper was meant to go.

You are dreaming you are driving your silver Audi TT convertible at high speed around winding coastal roads, only to wake up and find your foot on the sewing machine pedal and big swirly stitching all over your carefully cut out fabric.

You sew your sleeves together and somehow manage to create an arm hole right in the middle of your shirt.

Your carefully crafted trousers made from ridiculously expensive fabric somehow end up with three legs.

You can hear the whirrrr of the sewing machine, even when it isn't running;

You decide that hems don't really need stitching after all, a few pins won't hurt anyone.

You've sewn your pant legs different lengths and you seriously contemplate wearing different height heels instead of fixing the hems.

You honestly believe no one will notice if your child wears the shirt you just made with a collar on one side only.

You start considering sticky tape as a viable alternative to stitching.
