I believe the shank is pretty low and tight, I found out my machine has a tensioning knob to adjust the foot pressure, which will probably be helpful for future projects.
I managed to find a rolling foot here
though, I think it'll be less hassle all around to just go ahead and get one since it's not that expensive.
Lemuries, that does sound like a good technique, only issue is on my machine the needle is highly prone to mis-alighnment if the fabric is pulled while sewing, which causes the Dreaded Crunching Noise and bobbin snarls.
Ah well, I've got other things I can work on while waiting for the new foot. I'll report on whether the roller foot works when I get it.
