I discovered today that I can press 4 handles at the same time.
I put one piece of fabric on top of another on the ironing board, then do the same with another 2 pieces and put them a little way away from the first 2.
Press the first fold on one pair then on the other.
Press the second fold on both sets.
Do the final fold and press well.
Slide each set of handles apart.
Hey presto 4 handles in the time it usually takes to do 2.
Apologies if some of you already do this. Pressing is not my favourite job so I'm really please I've discovered this.
