I throw top soil in a wheel barrow and add a few cups of seed and mix thoroughly, then use that to patch bare spots....been doing this for years and works great. Lightly rake, put down mixture....water.
I used the stitcher for quite a bit...tried to roll each area multiple times, then applied seed. I did just like the video instructions.
I did an are in the front that was drier....then an area in the back that was after a light rain. Neither show great results after 11-13 days.
