cuffing/collar/interfacing/hemming/tucking/pockets/buttons/buttonholes/... so many techniques in a single (simple?) garment. shirts were my first real sewing class :) just like in math: theory is not everything, but theory helps. ordering passages helps, sewing the collar separately helps, practicing tucks does too.

and this is the result of a class that got me really really inspired (and got me buying a sewing machine).
