Not in quarantine yet... but I'll be doing the same as you!
I was remodeling my garage 6 months ago and never found time to finish. Half the walls are painted... my central vacuum is sitting on a bucket with the piping all taped up to the wall.... I never got around to finishing it, I figure this will be the perfect time.
I also plan on decluttering my house - I have way too much stuff I dont need, and no space for it.
the stairs in my house are the onlything I dont have done in hardwood, they wanted an arm and a leg to do them... But not I'm thinking of taking that project on also, thanks!
