Yes, at last!  I have received my Colemak keyboard stickers yesterday morning. I had ordered at least two sets of yellow stickers, for my black keyboard.  It was only a week ago I ordered them.  I was so eager to use them, I used my fingers instead of tweezers, which I couldn't find.
The 'T' and 'N' stickers had grooves in them, so I could feel the keyboard nipples.
I did not apply the stickers to every key.  I left the keys that didn't need them out.  That way it was easier to see which keys remained in the old QWERTY positions.
The reason I got the stickers, was so that I could use my one finger to type with, which is convenient sometimes, especially if you are standing up, over somebody,  or just can't be bothered to touch type.
It was tricky to type with one finger to begin with, but after a couple of days practice, I think that I am getting use to it.

I wonder if anybody, has received theirs?
