Dare I?

Three Irish Girls has put out a call for designs. 

I *love* Three Irish Girls.  A lot.  It makes up most of my stash and I can always find more that I want.

I have a couple design ideas.

Dare I jump in and go for it? 

I've never designed anything before.  I have a pretty clear idea of how each of the garments would look and how each part would be constructed, so I may just take the leap and give it a try.  What's the worst that can happen?  I end up playing with my favorite yarn and wind up having to find another pattern to knit it into?  I can handle that.
