This is exactly my thoughts. I call the rag quilt I made for hubby "green" because I used recycled everything except thread--shirts, jeans & batting scraps.

I also made a baby quilt with scraps of flannel and a leftover piece of fleece for the backing. I had just enough different colors of flannel to make 5" Trip Around the World block pattern with it.

Fleece is made out of soda bottles, so its "GREEN" also ;)

Seattle is very "green" territory, so I'll throw my perspective into the mix. A lot of the new hip/green moms around here would be very into wool batting. It's really nice to work with too. And while pricey, not as expensive as bamboo batts.

I guess it really depends on the individual couple as to how well they would like a baby quilt made out of recycled clothing from a thrift store. A lot of new parents are a little on the squeamish side when it comes to anything used touching their newborn (not as big an issue if it's from a family member). So you'd have to be the judge of that.

I also thing an all cotton quilt would be considered green.

Isn't cotton GREEN?

Green doesn't just mean using "organic" products. It also means to reuse, repurpose and save things from the past without using new items. So, using 100% cotton fabric from used clothing would also be "Green".

If they are going green with the baby, will they use cloth diapers. Much available for babies is not available "green", but I have seen organic cotton batting.

Isn't cotton GREEN?

Cotton is ordinarily grown with TONS of pesticides (think boll weevil, etc.).
I once fed cotton seeds to my goats, and had some customers--and my daughter--- react badly to the milk. Thank heavens not all my goats had freshened, so only a few were "contaminated" by the cottonseed feed!Those had their milk dumped for months....
I agree--the GREEN solution is to re-use and re-purpose--so I would re-cycle fabrics.

I don't have a clue about this, but a little more than a yard shouldn't set you back too far. Personally, I would think something that was made outof 100 % cotton should be green enough.
