Final update on the winter list:
My current status:
Build radiator cover for bathroom radiator - done
Build radiator cover for bedroom radiator
Cull/shred files - done
Cull/shred Mom's files - done
Organize cellar workbench
Declutter front porch - done
Caulk edges of kitchen counter where it meets backsplash (they used grout along this seam, but it should really be caulked instead)
I also need to transition to my new phone, which I'm dreading - done
List 4 items on eBay - done
So some of these items will get carried over to the next season, and the caulking might even get carried over to fall or winter since the grout is holding up OK for now. DH and I are in discussion about how to address bedroom radiator cover in a way that is aesthetically pleasing but doesn't significantly diminish heat flow (room is inadequately heated).
