TL;DR Do you expect stockinette in a silk/mohair blend (Tilia by Filcolana) to grow longer after blocking?

The complete story

Do you remember my fluffy WIP of doom? It was nearly finished before the holidays. But I ran out of yarn, with no hope of getting my hands on more of the same. Filcolana has apparently changed suppliers or something and the new lots look completely different nowadays (much more muted colours - I'm really happy I have the older version).

Anyway, I was absolutely devastated. So I took pictures of the sweater to show you, thinking I might take away some of the body length in order to finish the sleeves. Seeing the pics, however, I think I'm not mad at the proportions as they are.

Side note: Thank all the gods of knitting for TAAT, otherwise I'd have one sleeve and a half.

OK, now time for a confession: When I started this project, I didn't block my swatch. So I don't know how the proportions will change after blocking/wearing etc. I'm afraid that the sleeves will grow longer, ending up like too-short-full-length-sleeves instead of 3/4. In which case I should unravel a bit of the sleeves before doing the I-cord edge.

What do you think?
