Hubris. I plead guilty.
Purchased some nail guides to do some neat tips and so forth.
How the not-so-mighty are fallen........
Where did I go wrong?
A hubris as above stated
B did it in the semi-dark/dark
C didn't really look at it
D probably didn't check the guides had adhered properly
E in a bit of a rush to get it done
Oh, well. I have 157 more opportunities to do it (much) better. IRL it's not so ghastly. Suppose I can slap some glitter over it to fudge the dodgy edges.
