Sweater Dilemma

I just got back from a long weekend visiting my family, and because I got some really nice clothes while shopping, I was inspired to clean out my closet to make room for them upon my return.



I came across these two store-bought sweaters while doing so, and I was faced with a bit of a dilemma.



They are both 100% cotton, and both appear to be about DK weight. I recently read this page on recycling yarn from thrift store sweaters, and I wondered if I could unravel these sweaters of mine. (Click to enlarge photos).





I almost never wear the red one. Something about the bulkiness of it, the shape of the turtleneck, and the fact that it's too cropped. I doubt it will ever really look good on me, even though I adore the color and feel of the yarn.



This oatmeal one, however, I wear frequently... though maybe I shouldn't. It fits a bit like a sweatshirt, and the cables add bulk in places I don't really need it.

My question now, though, is whether or not these sweaters have serged seams.





I compared mine with the photos in that article and am still baffled.





The other aspect which keeps nagging me is almost a moral dilemma. I believe very strongly in donating wearable clothing to charity so someone else can get good use out of it.

A selfish part of me says "I'm donating boxes and boxes of other clothes - I'm allowed some DK cotton yarn from the process!" but then I still have a nagging conscience saying "These sweaters are already knit and pieced, and it could take you years to get to doing that. They could be keeping someone warm all this time."

So before I tackle that quandary, I figured I should at least query the internet regarding the seams: will it even be possible to unravel these sweaters? Any advice would be greatly, greatly appreciated.
