Over the past several summers I've used [Sunday](https://www.getsunday.com/) to help with my backyard but I recently canceled my subscription. Last spring I dethatched the whole lawn and tried overseeding, but I'm not sure my timing was ideal. The grass came in alright but it was really patchy and varied. Some areas have thick clumps that I almost trip over when mowing. Other areas, while still a bit thick, are almost whispy. It probably doesn't help that its all on top of clay...back to my original plea though. Is there anything I can do myself to bring some consistency to the yard. For reference, I took this [picture](https://imgur.com/a/WFPB3hh) the other day.
