The nose took me 9 hours. I am a psycho. I sewed on all of those little bits myself. When I was halfway through and pressed for time, I thought I should start gluing the bits on instead but then I realized it would look silly half-sewn and half-glued so I stuck it out.
I have always been a stickler for details and I hate half-assing my work, so gluing wouldn't have worked for me anyway.
