I'm always amazed at how impatient I get at the prep work. I think I get amnesia each time when it hits me that this phase takes so darn long! I'm itching to do the sewing, but can't get past the initial stuff. I poop out too when I should press on. (oops - no pun intended)
However, if I set up right the construction goes so easy. Also, a lot of times I am writing instructions for the classes I teach so I have to be orderly and clear so I can explain what to do for others.
