About four years ago, I made a shirt that mixed other fabrics with the small amount of an extremely late 80s/early 90s map print cotton(y) jersey. I went on to wear the shirt just enough to realize that the shape was very wrong for my tastes and layering propensities.
I kept the shirt because I did still like the ridiculous print, and I eventually moved it out of my closet and into the fabric stash, as much for potential re-use of the print part as because I was not going to just give away that much black rib knit. I can use that stuff.
Now that I've added the tank top from New Look 6766 to my sewing repertoire, I have a potential use for small yardages of knits. I dug out that shirt and found that I could just barely (it would need minor piecing at the hem again) squeeze the body of the tank top from the map knit in the shirt.
(the black rib knit used here was not that which was used in that shirt, but instead something thinner.)
