If you already have your things packaged up, no worries!
These were just tidbits of info passed along to me that I thought would be good ideas for us to follow. Not hard and fast rules, just suggestions. Trust me.....no one will send back their goodies if they are folded in a bag with a sticky label on them! LOL But I do get the suggestion. I reuse all the baggies I get, too.
It's all good!
