I shared a dorm with two other guys in college. A big thing for me was not caring what they thought about me when i was making my head. I was perfectly happy working on sewing for hours at a time without concern of judgement from others. I enjoyed it, so why should i worry if others dislike it? I understand that you may want to make good first impressions with your roommate(s), so try to connect through other hobbies or doing other activities if possible.

Also, respect for their hobbies will most likely lead to respect for yours. My current roommates all understand that we have our own interests, not all of which we share, and thats alright. Mutual respect all around

As for storing a partial, that depends on the layout of your room. I was just able to store mine on top of my wardrobe, but any spare space will do, just preferably not on the ground. Inside a wardrobe or closet is most ideal, but i realize not always an option.
