OK, so. After a nice long sit with my swatch and a stroll through Ravelry, I think I have a plan.
I’m going to go ahead with the kid sweater, but not necessarily set out to felt it, at least not right away. I figure it’s good to know that it has the potential to go through the wash without fully losing its shape, but I’m not sure how many washes it would have before fully disintegrating.
Anyway, here are my inspirations:
First, the In Stillness Mini. Such a lovely sweater- I love the simplicity of the broken rib and the stockinette. I think I’d like a different shoulder, and maybe a longer section of yoke.

And this adorable little sweater (Harry by Liudmyla Babintseva). I really like the vibe of this one, but I’m not feeling the fancy ribbing/cables right now, especially if I intend to felt this up down the line. I’d hate to do all that work and lose it by sending it through the wash. I love a Henley collar for kids’ sweaters. They look so fancy, and are great for fitting over gigantic melon heads.
So here’s my plan: I’m going to make a crew-neck/Henley sweater with set-in sleeves and a yoke of broken rib that goes just past the armpits. I want to make it as a top-down sweater so that I can use every last inch of my yarn (I’m about 90% sure that I have enough, but it’s going to be tight either way). I think I’m going to reach for my favorite Ann Budd pattern book since my kid is finally big enough to qualify for the kids’ sizes, and because I’m a basic b who pretty much just makes the same sweater over and over again.
What’s your favorite thing to knit for the kids in your life?
I love your planned sweater!
What sort of load did your swatch end up in? Hot, warm or cold water wash? Tumble dry on hot or just air? Since your gauge didn’t change much I’d probably block the finished sweater by soaking in cool water and drying flat after patting into shape to minimize initial felting. Then for ongoing care I’d try to toss it in a cold or lukewarm water machine load and lay flat to dry.
At least you know that based on your swatch the sweater will probably still be wearable if it ends up in a normal kid’s clothing wash and dry load occasionally.
Good luck – hope the sweater is much loved!
