My youngest likes green, vibrant green. During our last visit to Seattle (and finally realizing one can drool over Little Knits in person rather than just placing online orders), we purchased a skein of Cascade 220 Superwash. It is soft and spongy, but with a bit of an acrylic feel and susceptible to splitting.
Using an alterating 4-stitch cable pattern that crosses at different intervals (it resembles hearts) to make simple wrist warmers. Hopefully we can eke out a scarf as well. Unlike my daughter, I'm not a fan of vibrant green so crossing my fingers for no leftovers.
