superbleu, goaT,

+1 to the advice above.

If you use too much spray (as I did), the hard pressed felt will swell.

Mine dried with a hump in the middle of the strop (it was a paddle strop) - this did some evil things to my razors edge

Luckily, advice was posted on SRP that you could use a steam iron to flatten 'swollen' pressed felt strops - this worked a treat !

Have fun !

Best regards

Russ
