I donate all my pieced tops to PL. I rarely finish a quilt anymore unless I just happen to need a wedding gift or a baby is coming. Lately my line is dwindling so all have been going the PL direction. I did learn to keep receipts for EVERY Little Thing. My fabric receipts fill a gallon sized ziplock.
I learned to do this from my dad. Funny story here about his being audited in the late 50s. Two IRS men came to our dairy farm to audit his tax records. They questioned some tiny deduction for feed. He went to the cupboard and pulled out a paper sack, dumped it and plowed through the receipts until he found it. They didn't ask again. He even got more money back for the years they reviewed. I keep everything that the IRS might possibly want to see and then some.
