Break a project down into two week sprints?
And/or adjust your tempo to account for making stuff sustainable in both amount of novelty, intensity and progression.
Finding ways to get past the two week inspiration high is much of what makes an interest different from a hobby.
It’s also a super common ND thing, you might have utility of looking up their strategies for dealing with it?
But from my own experience, I have those two weeks to find something satisfying to do with the hobby, as well as figure out where it will fit in my life for the next 6 weeks or so, before I get bored with it and can’t pick it up again for at least a year. I’ve had to become very proficient in finding just enough materials, as well as getting rid of them, to not ruin me or drown in hoarded materials.
I’m also prone to taking on too many projects at once, having a two week quarantine period saves me an embarassing lot of times.
