I was planning to do so 2 weeks ago, but had to spend most of that time out of state.
My first experiment involved folding the gossamer from one bag in half longitudinally, then rolling it around a toothpick. Snip it in half; you now have two cartridge fills.
The draw is good, the hit is fine, the flavor is excellent and I'm not seeing any problems, but the 401 does have a small cartridge. 8-10 drops of liquid seem to fill the PTB (and I can't get used to writing that to mean anything but Powers That Be... but I'm a Whedonverse fangirl...) stuffed cartridge.
I plan to experiment with other stuffing methods once I locate a source for nylon gossamer or organza locally.
