Why Procrastinate?

I've been putting off a couple things that I *need* to get done craftywise. Jack has requested two embroidered belt flags for the Deepwoods Ascension Festival that our Dagorhir group is sponsoring. The event takes place in approximately a week and I haven't stitched the flags out yet.

I've found everything to do except these flags, including another medic flag, this one for myself

and a drawstring bag to offer as a prize at the festival.

But I still haven't done the belt flags and I spent a lot of time mulling over why I've been procrastinating and (confession time) I think it is because I'm not certain how to do them. You see, they are going to take some techniques that I haven't attempted yet including software manipulation, I am worried they won't look even half way decent, and also vaguely concerned that  my embroidery machine is going to have another one of its hissy fits. 

I think it also has something to do with lack of direction, being not sure where to start or how to plan it out. 

Therefore, the only thing I can do is sit my reluctant butt down and give it a shot, so tomorrow that is what I will be doing after work. Belt flags or bust!

What causes you to procrastinate and how do you get over it?
