It's very easy to buy more than needed and spend more than one "should"
A lot depends on what the household income and expenses are -
If one bought sewing stuff and didn't pay the gas bill - not a good thing.
If there is "extra" money for discretionary items - that can get sticky on who gets to spend it.
I buy in spurts - I can go for a while (now) without buying anything - I've been in and out of JoAnn's and Hancock's- and not seen a thing I wanted badly enough to buy. I do "binge" sometimes when WalMart's seasonal fabrics go on sale. I have a pretty good stash of Halloween fabrics now.
But I have years of accumulation staring at me - and I remember going through my Mom's stuff - - - -
I can relate to the need/desire to acquire - - -
It truly can act like an addiction.
