Tack down round
Place the hoop back in the machine with the stabilizer still hooped and the trimmed or pre-cut fabric on top of it.
The machine will now secure the fabric in place with a second round of stitches.
Another stop after this second round allows you to remove the hoop one last time for extra trimming if necessary. Place the hoop back again.
A third round of zig zag is now done to lay a base layer for the top stitches.
