finishing work

I am coming to the end of a project. this has been a series of embroideries that I don't know if they have worked or not. I have one more to do and I just can't get going. I know what I need to do. by now I have worked out the formula, the different stages.... but I also know that once I have finished this piece, it will be time to look at the whole series. examine what works, and what doesn't, tweak, refine or just face what I have made. and that is scary and best avoided. sigh.
