Men's chunky sweater
This is a nice quick and easy knit from Yarn Forward. I knitted the second size of it in Sirdar Peru chunky, which needed exactly ten balls - ie 900m. And by exactly I mean I had six inches of yarn left after casting off and had to buy some tapestry wool to sew it up with. The decreases up the raglan shoulders are very attractive and well-explained in the pattern. I would advise using the loosest bind-off you know as otherwise your recipient may have trouble getting the sweater over their head.
