What Momma has time for a True Hobby?

As Christmas (and my birthday) rolls around my husband pointed out to me that it was hard for him to pick out gifts for me as i don't seem to have any hobby's.
I'm a stay at home mom with only my husbands income, which pays the bills and allows some eating out but if i were to indulge in the hobbies that spark my interest we would be shelling out another $100 a month, and currently i just cant swing that.
As i play on Facebook - which i should mention is currently my at home hobby. I realize there are few things i'm even interested in. Id like to learn Spanish, i love being with my kids, pottery would be fun, and as an optician i am always drawn to eye wear.
I love working out and I like taking classes and being with other people with like minded interests. it motivates me to do better and be more.
im also totally into fashion, although i dont get caught up in it and to focus my intentions and time into fashion would frusterate me as i know looks mean nothing in the long run and always fade away...
i used to love baking and cooking, but now i just find it more of a hassle.
so thats my rant for now...
