I turned the vest inside out and sewed across the bottom leaving enough of an opening to turn it right side out.
Then I practiced some buttonholes.
Then I stitched the button holes. I cut them open with the seam ripper and sealed them with clear nail polish.
I LOVE the one step button hole all I have to do is place it where I need it and push the pedal and watch it sew.
The rest of this should finish up easily since I only have to sew on the buttons, sew the hole shut and iron it.
