I just tried this with bulk ODF and the folding results were so-so. I had the flake to my preferred level of dryness, the folded OK but kind of broke apart with the rolling part. Still, I was able to get a some what managed pack into my Peterson ebony 106.
I am with masspiper in that I seem to get my best results from rubbing flakes into a nice shag. Cube cutting never seems to do it for me and have had mixed results stuffing a whole flake into a bowl. This method seemed to work better, so maybe there is hope for me yet.
Thanks for posting the link, Dan!
