@LeGaosaure I like turning scraps into mitred square blankets like this one (made of fingering-weight scraps).
I normally pick up and knit each square, so there's no sewing squares together.
There's a fair bit of sewing in ends, but I tend to knit 10 or 20 squares, then sew in the ends, then knit more squares. So there's no marathon of sewing in ends after all the knitting is done
