Assuming this is meant to be Christmas-related...of course the very most budget-friendly idea is to spend less on Christmas. It's kind of a running joke with Ev and Liss that every year, Cheryl and I announce somberly that this year, we are really cutting back on Christmas presents and this year we mean it! But then the piles under the tree are as big as ever. It just never seems fair to the younger kids that the older kid/s got the full Christmas and then we started cutting back by the time the younger kids bothered to show up.
But that aside, the thing we've done, and by "we", I mean Cheryl, is that about 4 years ago, she spent every available hour in the weeks leading up to Christmas making some simple drawstring Christmasy bags to "wrap" everything in. Of course, I say they are simple, because I wasn't the one making them. They are really cool, and they sure make the wrapping process so much easier and faster.
They save us a fair amount on wrapping paper and related supplies, but that said, I think the main reason Cheryl made them was for environmental reasons, so there are fewer trees cut down and plastic-ish wrapping paper hitting the landfills.
