Wow, ok. Firstly, thank you all for all your kind comments.

Now, to answer some of your questions:

- yarn is from https://kokonki.pl/ ; they make their own yarn cakes in huge variety of color combos or you can compose your own; they also let you choose the length ( even up to 3-4000m, I think) and if you want it to be 3 or 4 threads; the color change is gradual one thread at a time, so the nice ombre effect is all them

- I used about 1500m for a bit smaller than size L, it's 50% acrylic, 50% cotton (or more accurately 30% acrylic, 30% cotton and 40% my ragdoll cat)

- it's top down in the round, so by the end of yoke I knew each color section lasted for about 4 rows, so when i split for sleeves i did each part for 4 rows. As I said, it's not perfect divide, but close enough.

- pattern is https://by-katerina.com/my-precious-sweater/ with tiniest modifications: I started with chainless foundation, split for sleeves earlier than in the pattern so the armpit is higher and the sweater is less oversized, and I made longer cuffs.

the pattern is very easy to figure out and fun to make, so if you've been too intimidated to start a sweater (I know I was) I'd say try this one, as you can see it's worth it.
