I found
inspiration for this hat while reading AARP, Feb/March 2015, p11, STAND BY FOR PIE, “After
a 100-year wait! March 14 offers math geeks - and pastry lovers –
a once-in-a-century pleasure. On 3/14/15 at 9:26:53a.m. (and p.m.!)
the date and time will reflect the first 10 digits of the
mathematical constant pi (π).
Many bakeries and pizza shops will have specials to make the day.
Princeton University will hold an Albert Einstein look-alike
contest.”
Pi Ripples Hat will start
in the top with an I-cord, in honor of Albert Einstein, and work
through (2)radius x pi to give the desired circumference. You'll be
creating a circular crown by making 10 increases every other round,
then you'll be ready for the 10 stitch repeats of the modified lace
pattern Ripples, 400 Knitting Stitches, by Potter
Craft, p205.

Notions:
Stitch
markers, tapestry needle
Abbreviations: k
= knit p= purl Rnd/s=round/s yo= yarn over
k2tog=knit 2 together k2togbl=knit 2 together through the back loop
st/s=stitch/es CO=cast on
M1= make one stitch (Helpful hint: I prefer
the M1 (m1tbp):
place point of working (right-hand) needle behind other needle,
inserting needle from the top through the purl stitch below next
stitch, and knit, then knit the stitch above.)
Special Stitches:
These 10
stitches and 16 rows make the Ripples pattern:
Rnds 1-5: Knit 9, purl 1
Rnd 6: K3, k2tog, k3, yo,
k1, p
Rnd 7: K2, k2tog, k3, yo,
k2, p1
Rnd 8: K1, k2tog, k3, yo,
k3, p1
Rnds 9-13: Knit 9, purl 1
Rnd 14: K1, yo, k3,
k2togbl, k3, p1
Rnd 15: K2, yo, k3,
k2togbl, k2, p1
Rnd 16: K3, yo, k3,
k2togbl, k1, p1
Directions: Have
fun! The pattern is written as a mathematical and knitting
challenge.
(Not really, but it was
a challenge for me to start, work, and write directions for a
top-down hat! Notes are in italic. Have fun!)
With US#7 double pointed
needles CO 3stitches work I-cord for 3.14”.
(Finishing: Tie I-cord
into a knot, or fold down and stitch as a loop for a finial.)
Crown increases:
Rnd 1: pm, M1, k1, M1, k1,
k1 5sts
Rnd 2 and all even rounds:
Knit
Rnd 3: * M1, k1; repeat
from * to end 10sts
Rnd 5: * M1, k1; repeat
from * to end 20sts
Rnd 6: Knit work to US#8
needles. (If using 2 circular needles, 11 and 9 stitches per
needle)
Rnd 7: * K2,
yo; repeat from * to end 30sts
Rnd 9: * K3,
yo; repeat from * to end 40sts
Rnd 11: * K4, yo;
repeat from * to end 50sts
Rnd 13: * K5,
yo; repeat from * to end 60sts
After Rnd 14: measure the
2(radius), and multiply by pi (3.14) to determine if hat
circumference is suitable for an infant. (I measured and
calculated: 2(2.25”) x 3.14= 14.13” circumference for an infant.)
If desired, continue working increases as established (measure
and calculate after the even/knit round) for a child or adult
sized hat.
Rnd 15: * K6,
yo; repeat from * to end 70sts 2(2.5”) x 3.14 =
15.7”circumference; toddler
Rnd 17: * K7, yo;
repeat from * to end 80sts 2(2.75”) x 3.14 = 17.27”
circumference; child
Rnd 19: * K8,
yo; repeat from * to end 90sts 2(3.25”) x 3.14 = 20”
circumference; teen/adult
Rnd 21: * K9, yo; repeat
from * to end 100sts 2(3.5”) x 3.14 = 22” circumference;
adult
Hat: With US#8
circular needles, set up Rnd 1: * knit 9, purl 1, pm; repeat from

Rnd 16: * K3, yo, k3,
k2togbl, k1, p1; repeat from * to end
Follow Ripples
pattern/chart: infant 5”,6”; child 7”; adult 8”,9”; ending
on rnd 3, or rnd 11.
For
a taller hat, or fold-up brim work extra rounds of pattern before
starting the brim.
Rnds 1-10: * K1, p1;
repeat from * to end
Bind off loosely in
pattern. Weave in tail.
Finishing:
Tie I-cord into a knot, or fold down and stitch as a loop for a
finial.
