I use selvedges even if they don't have the dots, though the ones with the dots are prettier I think. I like them because they don't unravel, so I will use the actual selvedge site for my QAYG blocks and I only have to sew down one side. I think I have a pic of this somewhere, I'll see if I can find it for ya. I say, save em and if nothing else you can use em to stuff a pillow with!!
Cheers!
