Sleeves
Using DPNs, co 24 [27, 33, 36]. Divide sts evenly over 4 needles.
Place marker and join [being careful not to twist work] and work in k2, p1 rib for 2 [2.5 , 3, 3.5 ] inches. Change to St st and inc 1 st on either side of marker every 2 [ 1.5, 1.5, 1] inches for a total of 8 increases. 40[43, 49, 52] sts on needles.
Note: Change to 16-inch circular needle when there are enough sts to work comfortably.
When work measures 16.5[17, 17.5, 18] inches, knit to 3 sts beyond the marked st, then slip the last 7 sts worked onto a piece of contrasting yarn.
Put remaining sts on a stitch holder, a length of spare thread or spare circular needle of any size; break yarn leaving a 12-inch tail and repeat for other sleeve.

Body
CO 108[124, 140, 156] sts using 30-inch circular needle.
Place marker to indicate beg of the round [marker A], join [being careful not to twist work], and work in k2, p1 rib for 54[62, 70, 78] sts. Place another marker [marker B] to indicate the opposite side; it will be easier to differentiate the two markers if they are different colors. Continue in k2, p1 ribbing until piece measures 2[2.5, 3, 3.5] inches.
Working stripes as indicated by chart A, B or your own mood, switch to St st and work until body measures 15[16, 17, 18] inches from cast on edge.

Join arms to body
Join MC to body and k 1 rnd.
K to 4 sts past marker A, then slip the last 7 sts worked to a spare length of yarn.
Cont in St st until 4 sts past marker B, then place the last 7 sts worked onto a holder and complete the round.
At this point, you will have 47[55, 63, 71] sts each for the front and back and 33[36, 42, 45] for each sleeve. 7 sts are held on spare yarn at each underarm and at the top of each sleeve. These sets of 7 sts will be lined up with each other as you join the arms to the body and grafted together during finishing.
Attach first sleeve by knitting the 33[36, 41, 45] sleeve sts onto the same circular needle as the body sts. Every time you come to the 7 held sts, just leave them hanging inside the work. You'll deal with them later.
Continue in St st until you come to the second set of sts held on spare yarn and attach the second sleeve in the same manner. Finish round.
Work in St st over all 160[182, 208, 232] sts for 4 rounds, placing markers at each of the four points where body and sleeve sts meet.

NOTES:
If you use a different colored marker for Marker 1 and place it just BEFORE the set of underarm stitches, the beginning of your rounds will be easy to find.
The first few rounds after you've joined the pieces will be a bit tight and awkward to knit, but it will soon right itself.

Begin raglan decreases
Rnd 1: From marker 1: k1, k2tog, then *k to 3 sts before next marker, ssk, k1, slip marker, k1, k2tog* repeat at 3rd and 4th marker, knit to 3 sts before marker 1, ssk, k1.
Rnd 2: K around with no decreasing.

For Theresa's mock turtle
Work these 2 rnds a total of 15[17, 19, 21] times until you have 3[2,3,3] sts remaining between the markers over the sleeves: 40[46, 56, 64] sts. [At some point, you will have decreased enough that you may want to switch back to the DPNs for knitting comfort.]
Work one round plain, dec 1[1, 2, 1] st in order to have a number divisible by 3 for the ribbing: 39[45, 54, 63] sts. Work in k2, p1 rib for 2 inches or until desired length of turtleneck is reached. BO loosely, following rib pattern.

For Amy's boatneck
Work these 2 rnds 11[13, 15, 17] times more = 64 [70, 80, 88] sts.
BO loosely.
