I used to bury the fabric receipts deeeeep in the trash bag but now, since almost all the quilts I make are for charity, I keep track of those receipts because I can deduct them from my taxes. I also traveled 2,040 miles last year for non-profit quilting purposes, tax-deductable as well.
When I told my tax preparer my numbers I feared DH would have a heart attack, but he managed to survive... With gas prices going up so high he's started making ugly noises about my monthly gas costs.
