My husband has way more $$$ spent toward his hobbies than I do, but I never thought of it as a lot because he purchased in bits and pieces, not all at once. I suspect many quilters do the same, or save for the big purchases.
He used to urge me to get a hobby so I wouldn't be bored in retirement. I always told him not to worrry, I'd find something to do. Imagine his excitement when I took his advice and started quilting...imagine his waning enthusiasm as I purchased fabric and tools and spread out my hobby through our home - just like he'd done for 30+ years with his hobbies. He's still very supportive, but I can tell when he's mentally kicking himself for ever suggesting I get a hobby!
