I'm a pretty new knitter about to felt for the first time too. I've tried felting a few swatches before knitting the project (clogs, obviously

I'm a bit confused as to what exactly the final felt should look like. In the samples I've felted, the stitches disappear under the felty fuzz, but I can still sorta make them out when I press the fabric between my fingers. Should the felting turn the knitting into a homogeneous mass where the stitches complete dissolve? Or is what I'm getting what I'm supposed to be getting? (Somebody also mentioned that some 100% wool yarns felt better than others, depending of how they've been treated in production, etc.)
Well I hope this isn't long and insane.
Thanks!
