Hmmmm I keep mental note of how much I spend but I do not tally it up, all I know is I do not spend nearly as much as hubby does on his "hobbies", I don't say a word about how much he spends, and he does not say a word about what I spend. I am in charge of both the personal and business finances, so I see what he spends, though I am definitely the saver in our household and sometimes I do have to tell him "no extras" this month, and then he will ask when he can "spend"again.
I just started quilting last year and I am new, my initial investment in tools, books and fabric last year has set me up for this year. I have several projects that I want to do this year and with the exception of some backings, I will not be spending much on fabric this year as I have other areas where I want the money to go.
