I designed it as an approachable easy first garment: simple stockinette, minimal shaping, and an easy boat neckline.
Layer it with a cami when it’s warm or add your favorite denim jacket when the temperature drops.
That’s what I love about knitting… we can create clothing that works for our lives and our lifestyle.

Notes:
- Decrease until you’ve reached your desired width, knit in stockinette until you’ve reached your desired height.
- Place a stitch marker at every decrease, so it’s easier to see and match both sides.
Optional: Don’t bind off and set aside until the other half is complete, so you can sew up the sides and see how deep you’d like the arm hole and add more stitches to desired length/depth. Make sure the overall fit is desired/perfect.

BO in the K1, P1 pattern, leaving an 8″ tail to sew the top edges together for the neck hole.
Knit a second panel from the beginning, following all the instructions above.
Both the front and back are identical.
Finishing:
With your bound-off tail, sew 2-3 stitches together at each shoulder, working from the outer edge inward. Leave the center section open — this becomes your neck hole. Try it on as you go to get the opening just right for your style preference.
Sew up the seams before steaming:
Using 2 strands of the brushed mohair that’s twice the length of your seam, carefully sew the seam, being careful not to tangle up the yarn, from the bottom edge to the first decrease stitch, marked by a stitch marker.
Weave in the ends.
Steaming:
Don’t skip this step. Steaming really pulls everything together, turning it into something you’ll feel proud to wear again and again.
Lightly steam the finished piece to even out stitches and encourage a relaxed drape. Steaming helps smooth out uneven tension, soften the fabric, and allows the garment to relax into its final shape and measurements before wearing. This final step gives the piece its signature drape and finish, transforming it from handmade to beautifully finished.
