Things no-one told me about sewing...

• you will need to iron a lot.  I mean a lot
• a nice chunky knitting needle is the bee's knees for pushing out corners
• you will wish you had been born with a quick-unpick as a spare limb
• re-threading the overlocker could lead to the need for therapy
• the bobbin will run out of cotton right in the middle of a main seam - usually the front neckline
• no matter how many buttons you own, you will neeeeed more
• did I mention the ironing?
