it would be considered contents if there was ever cause for a claim. my insurance guy told me to keep my receipts with other tax papers in a safe place. most policies allow a certain amount for different contents. the more documentation you have the better. such as your sewing machine, if you have no documentation and claim sewing machine they may only allow $50 (just an example) if you paid $5000 for it you want to be able to claim that and make sure you have replacement value on your policy that way if you paid $7.95 a yard for fabric then find it is now $10.59 a yard you can still replace it...
