If you keep small appliances on your counter, make covers for them. Curtains for the windows. I even have short curtains on all my windows and doors in my garages to spruce them up. Just because they're a garage doesn't mean they can't be pretty too. Hot pads, table runners for each holiday or season. I made a small cover to go behind my head for my recliners as when I come from outside from working hard, my head might be sweaty and if I lay back on my recliner to relax, this keeps the sweat off the chair and onto the cover. Also, my cats like to lay on the top of the recliner so this also keeps the hair off.
Might make a lap quilt for the car to take from short or long trips, trash bags for the car.
