Ah, indeed I iron the yoke just after the collar. Phew.
Now tricky things are dresses. My daughter (only 18 months) has a few, and they require a bit of dexterity.
T-shirts can be particularly frustrating, as many appear not to naturally lie along the seams. I have no idea why, but it is very frustrating!
Some socks also seem to get stuck by static in odd positions, requiring a hand down them to separate the two sides, then a deft whizz with the iron.
I used to iron Y-fronts, doing the but betweeb the Y first, then the edges. Mostly I have briefs now, but have stopped ironing undies now.
