Here are lots of different patterns for storage and covers of all types and sizes.
If you want to keep your sewing machine out instead of put away in the case, here's how you can keep it clean and dust-free. Sew a cover that will coordinate with the colors of the room you sew in. I used to order quilted pillow shams when i used to sew lavender sachets and they frequently come in pairs which should be enough for a cover. or, if you prefer, fleece is pretty affordable at Joann's these days. Or, any quilted fabric would be nice and would hold its shape well.
In addition to that, there is another pattern package for closet accessories that would be nice for a housewarming gift or for your daughter who will be going off to college. Some bedrooms are so small these days, these would help store lots of things while keeping them visually accessible. I don't know anyone who has that many umbrellas who doesn't live inSeattle. You could skip a couple of seams and store other larger things in that hangup.
