Ooops! I’ve been money laundering!

As I can’t get out today without my car (hopefully after they put in a £200 replacement thingy!  I should get it back today) so I hoped for inspiration, when I took the washing out of the dryer (it’s raining) I hate tumble drying but needs must. But £5 x£1 notes came flying out of the dryer, all washed and dried, so what pile do I put them in? The ‘folding is good enough’ pile or the ironing pile? We still use £1 notes, better than all those 
heavy £1 coins.
