I washed the trainers DS needs for PE. At the same time, and then they were dried in the same place. On a large windowsill, a large sunny windowsill with nothing overshadowing - both same amount of sun.
This was on Sunday afternoon.
One was bone dry the following evening, the other is still damp. I've since swapped them round several times, just in case, but the other is still damp. Damp all over, not in a specific place. Nobody has touched the damp one (and why would they?)
I have now resorted to the hairdryer and the fucking thing is still slightly damp.
Why? Why....?!!! I am baffled. I can honestly think of no logical explanation!
