Arc Shawl BUY THIS BUNDLE

The Arc Shawl unfolds like the open sky at daybreak, a half-circle of SAVE TO FAVORITES
warmth in a graceful sweep across your shoulders. Cast on with our
Arc Shawl Bundle and knit together the unparalleled softness of PRINT 28 COMMENTS
Season Alpaca with the delicate haze of Tussock for a fabric that
glows with the beauty of both yarns!

Our Arc Shawl pattern draws on Elizabeth Zimmermann’s famous Pi

Shawl formula, where increase rounds ripple out from the center,
alternating with ever wider sections of stockinette as the circle
grows. Here, that idea has been reimagined into a celestial
semicircle!

You knit with Season Alpaca and Tussock held together throughout,
working the shawl flat from the center out. Lots of simple
stockinette stitch makes for an easy and meditative knit, giving you
plenty of time to admire the dreamy fabric forming on your needles,
while yarn-over increases shape the arc and create rows of little
eyelets. Stop early for a cozy, smaller shawl or keep going for a
dramatic wrap that enfolds you from shoulder to hip!

Bringing a fluid drape to the fabric, Season Alpaca is the very

essence of alpaca-fiber softness. Spun from the finest grade of
hand-sorted Peruvian super baby alpaca, this smooth, multi-strand
sport-weight yarn glows with its own inner light across a palette of
glorious, gently heathered shades.

Floating alongside is lace-weight Tussock, 60% super fine kid mohair

and 40% mulberry silk, a beautiful blend for absorbing color and
reflecting tones. The mohair lends the shawl its luminous halo and
decadent warmth, while the lustrous silk adds shimmering richness.

Together, these yarns transform into fabric with both gravity and
lift, substance and radiance. We created 13 beautiful Arc Shawl
Bundles (you can see swatches of each one above!), including the
stunning pairing of Season Alpaca’s True Turquoise and Tussock’s
Lapis Lazuli… A shawl as brilliantly blue as a cloudless sky!

Choose the palette that calls to you and watch your Arc Shawl open
into an expansive curve that carries the spirit of the horizon in every
row.

have swatches for the color mix bundles, such as the pink and
orange. Thanks

Approximately how long does it take to knit the Big Shawl?

reply

Gavriella says:
September 18, 2025 at 6:38 pm

Hi Kim,

That’s a great question! Unfortunately since we all knit with

different styles and at different paces, its difficult to provide
an estimated time frame for handmade projects. We
encourage you to give it a try and we’ll be here to cheer you
on and answer any questions along the way!

Warmly,
Gavriella

Natalie says:

How pretty!
Is the smaller version just the large version but knit shorter in
length, or does it retain the same proportions of the different
segments? I hope my question makes sense and you understand
what I’m asking. … is each section a little shorter in length or is
 just the last section shorter?

reply

Gavriella says:
September 18, 2025 at 6:40 pm

Hi Natalie,

Great question! The proportions are the same. For the larger
shawl you will just work one more increase row and continue
knitting more rows for a larger result.

Happy knitting,
Gavriella

Natalie says:

I see. So they are the same measurements until you get to

the last section. Thanks!

Hi Judy,

I’m afraid that we don’t have photos of the smaller version

but you can find all of the sizing measurements in the SIZES
section of the pattern to help give you a better idea of the
result. I hope this helps but please let us know if there is
anything else we can answer for you!

I absolutely love this pattern but being in Florida this would be a

bit warm for our climate. Is there a yarn I can substitute that is a
lighter weight realizing that the shawl will be smaller in
dimensions.

reply

Gavriella says:
September 18, 2025 at 6:47 pm

Hi Sharon,

Thank you for writing in! We totally understand the need for
adjusting for warmer weather. I’d recommend Cotton Pure as
the perfect alternative so that you don’t have to sacrifice size
at all! From there you will just want to make sure you can
match the gauge of the pattern and you are ready for a
Florida fun shawl!

All the best,

Gavriella

reply

Sharon says:
September 19, 2025 at 6:44 pm

Thank you so much. I have and love cotton pure. Would

you suggest putting the mohair with it realizing it will be a
little warmer but not nearly as warm as the alpaca. I do
have the color beach rose. Is there a color of Tussock you
could suggest that would go with this color.

Thank you

reply

Gavriella says:
September 22, 2025 at 10:39 am

Hi Sharon,

You are very welcome! I wouldn’t pair Tussock with

Cotton Pure just because the fibers are quite
different. Pairing a plant fiber with a animal fiber can
sometimes lead to the stitches growing at different
rates during the blocking process and with normal
wear. Luckily the mohair doesn’t add a ton of weight to
the strands so you should have no issues getting gauge
with the Cotton Pure alone. If you do decide to go with
a strand of Tussock though, I’d recommend Tea Rose
or Alizarin Orange for great contrast.

Happy knitting!

Hi Rose,

We’re so sorry to share that we don’t currently have a

crochet version of this pattern. Thats such a great suggestion
though and I will be sure to share it with our team for future
pattern consideration!

All the best,

Gavriella

Sharon says:

I love the yarn over detail, but won’t need the extra stitches on
the final yo instruction, as I’m making the smaller shawl. Still, is
there a way to include the yarn overs without doubling the
stitches, as they add so much visually! Thank you!

reply

Gavriella says:
September 22, 2025 at 11:32 am

Hi Sharon,

That is a great idea! I’d consider working a (YO, K2tog) repeat

on the right size to get a nice row of eyelets. You could try
this out over a small swatch first to see how you like it!

All the best,

Gavriella

Sharon says:

Hi all,
I used Gavriella’s suggestion above, yo, k2tog, and it came
out beautifully! My only complaint with this pattern is, as I
feared, the edges really roll up, it is hard to see the final
detail of yo’s at bottom. Would an i-cord help fix this?
Thanks!

reply

Gavriella says:
October 9, 2025 at 10:09 am

Hi Sharon,

I am so happy it was a success! I think an icord or even

a few rows of added garter would be great to help that
edge stay straight!

Please let me know if there is anything else I can do for

you!

All the best,

Gavriella

I love this pattern and am looking forward to starting in when I

receive the yarn. I have a circular needle kit that can go up to 32
inches. Will that be long enough for the big shawl or do you think
40 is needed.

reply

Allison says:
September 24, 2025 at 10:58 am

Hi Jen,

We’re so glad you like the pattern! Shorter length needles

will work for the first part of this shawl, but with the increase
rows, we find the stitches can feel quite crowded on the
needles, which is why we recommend switching to 40”
needles at that point. You may want to try your 32” needles
and see if your stitches feel comfortable on them, switching
to longer needles if necessary.

Happy knitting!
Allison

What a superb shawl! I have noticed that the section above the
longest one it looks as though it was knitted in either a slanted
stitch or a different yarn. Is there a reason for this?

Thank you
!

reply

Allison says:
September 24, 2025 at 1:47 pm

Hello,

We’re so glad you like the shawl! It may be surprising, but all
the sections of this shawl are made with the same yarn and
stitch pattern! The sections may appear different because of
how this shawl drapes. The longest section of the shawl has
an almost undulating look, while the middle section is pulled
smooth. We love that a simple stitch pattern can allow the
yarn to shine through in this way and we think it’s wonderful
that your eyes caught that little detail!

All the best,

Allison
