since i have taxes to do every year, i keep very good records of my expenses, last year was my first year to actually bring in more from quilting than i spent on supplies...but that i think is just a fluke :-D since i plan some long-arm upgrades this year. but yes i keep every receipt and keep track, there have been a couple years that were (wake up calls) where the spending was way out of control, but seeing it in black & white helped get it under control :thumbup:
