I've seen some funky videos where at the beginning you sew a couple of stitches in then bring the tail forward under the foot then sew over it a little then let the knife cut off the excess.
At the end of sewing, the fabric is flipped over, tail brought forward and then sewn over.....but then your stitches are different on one side. Maybe feeding in with a needle is the easy option.
It's all new to me, trying to get to grips with the basics.
