I can't really make anything major these days—sewing-, knitting-, or otherwise-wise—but I did manage to rig up a canopy over the bug's bed the other day, to trap heat, absorb sounds (in particular this bizarre new sound she makes whenever she's standing up, and most other times too), and to make her area a little cozier: twelve-foot ceilings are pretty but decidedly uncozy.
I suspended two shower curtain rods from the ceiling (which is beadboard, so it's easy to screw hooks into), and braced them apart with a piece of bamboo I found in the pantry. Then two sections of material are draped over them and kept from slipping with a little double-stick tape. Impermanent, maybe, but it works. The mobile is a bit of a fly in the ointment, but eventually I'll get around to fixing the height so it clears the canopy but is still out of bug reach. So far the canopy has not improved anyone's sleep. The bug is waking up every two hours to stand up and growl in the dark.
