This is so relatable. My jumper made especially for Winter 2022 is still waiting for another sleeve and a half, and the cross stitch project I confidently planned to finish "by Spring" is just about winding up now.
You can do it though! I believe! And remember if you finish it in time to wear it once before the weather turns, you technically won π
p.s. how are you finding that yarn? I made a top from cotton/linen blend a few years back and it's lovely to wear, really softened up in the wash. But the linen made it absolute murder on my hands during the knitting process. I'm wondering if the addition of viscose makes it a bit less horrific to work with.
