I usually like Mondays, the feeling of a new week with new forces!
Today is not that kind of day.
You know when you really are should go to bed, but have so much to do so you shit in the mood and work on instead?
The result is that everything works wrong, and in the end you have spent twice as much time and energy on something that would have been very simple - if you had done it another day.
So now, after a number of hours in the sewing room, I'm going to spend the evening doing that crack! :)
