Took some photos of Dc and you can see every crease in their t-shirts 😳
I've dug the iron out (MIL's old one) and my flimsy ironing board with equally old cover.
Ironing on steam setting cotton even though most clothes say level 2. T-Shirts don't look much less creased than before 
What is most important when ironing? If I replace something should it be the iron, the board or would a decent cover be enough to make a difference?
