Made this for my 2 yr old last week. It’s made of Sugar ‘n’ Cream worsted wt cotton on 4.5mm needles (aka “us sz 7”), 40cm circular and 20cm dpns. Top-down raglan, both body and sleeves in the round. I used german short rows to add height to the back of the yoke. I used mirrored “knit-below” increases–not sure what the standard name is in patterns, but they are my favorite general increase. The sleeves used centered double decreases along the underside. No pattern, so there was a bit of math involved, but that’s what I love about top-down raglan: it’s pretty flexible and adaptable as well as attractive and shapely. If I did it again, I’d probably make the neck hole a tad smaller though and the button slit a tad longer; it fits fine though, with room to grow.
He likes it, but asked for help taking it off after a few seconds: “off! hot!” So now, just have to wait for winter!
