The yarn is very soft and cozy, but has a tendency to stretch (as superwash is wont to do). That doesn’t bother me with baby knits, but I’m not sure I’d use it for a sweater for me. I might actually prefer it to Knit Picks Swish, the superwash I use for baby shower knits all the time.

The pattern is easy and would be good for a newbie knitter, though it does call for you to kitchener stitch the shoulder straps together (though honestly you’d be fine just binding off and seaming, and it would probably give the straps a little more structure).

Update:
Easy to slip on over Erik’s head, and very cozy for him to wear!
