Knitted Digestive System Pattern

WARNING - This pattern has not yet been tested in its entirety. I am in the process of making a second digestive system while revising the pattern and taking instructional pictures. These are my notes from knitting the first one and may be unintelligible to anyone else. If you are serious about making your own Knitted Digestive System, I suggest you check out the Craftster Knitalong. There I am gradually posting sections of the revised pattern as I complete them. Craftster membership is not required to view the posts (but strongly encouraged!).

 

Yarn (the yarn I used is in parentheses, but this is only a suggestion)
Angry Pink: Worsted Weight, 1/2 oz. (Caron Simply Soft Brites: Papaya)
Mellow Pink: Worsted Weight, 2 oz. (Red Heart Super Saver: Rose Pink)
Shiny White: Sport Weight, 1/4 oz. (Bernat Baby Coordinates: Natural)
Yellow-Pink: Super Bulky Weight, 6 oz. (Red Heart Baby Clouds: Creamsickle)
Soft Pink: Bulky Weight, 1 oz. (Bernat Softee Chunky: Pale Antique Rose)
Burgundy: Worsted Weight, 1 oz. (Red Heart Super Saver: Burgundy)
Green: Worsted Weight, 1/4 oz. (Red Heart 4 ply: Emerald)


Anus

With size 6 dpns and Angry Pink, cast on 10 sts using a temporary cast-on, join. (If you don't know how to do a temporary cast-on, just cast on normally using waste yarn then knit 1 row with Angry Pink).
Knit 8 rows.

Pull cast-on edge up through the middle of the dpns. Slip a few stitches off the waste yarn and onto a spare dpn (I find it helps to use a smaller size). Next knit every stitch together with a stitch from the cast-on edge, slipping cast-on stitches from waste yarn onto the spare dpn as needed. Place a stitch marker to mark the beginning of the row.

Rectum

K3 rows plain.
K3,M1,K3,M1,K3,M1,K1 (13 sts)
K2 rows plain.
K4,M1,K4,M1,K4,M1,K1 (16 sts)
K2 rows plain.
K4,M1,K4,M1,K4,M1,K4,M1 (20 sts)
K12 rows plain.
K5,M1,K5,M1,K5,M1,K5,M1 (24 sts)
K6 rows plain.
Next row: *K12, turn, P10, turn, K8, turn, P6, Turn* K24 and repeat from *to*.
K2 rows.
Over the next 4 rows gradually switch from Angry Pink to Placid Pink as follows:
Row 1: Knit every 3rd or 4th stitch (aiming for a random appearance) from Placid Pink, carrying both yarns inside the work.
Rows 2-4: Knit all Placid Pink stitches and random Angry Pink stitches which neighbor them with Placid Pink, gradually replacing all Angry Pink stitches with Placid Pink.
Row 5: Break Angry Pink and knit all stitches with Placid Pink.

Large intestine:

K4 rows.
Determine stripe placement. Position rectum pointing downward, with one short-row bend facing you and the other to your left. The intestine should bend to your right and slightly upwards. One stripe should be placed facing you in the middle of the intestine. Knit to this place in the round.
*K1 Shiny White, K11 Placid Pink, K1 Shiny White (FROM THE OTHER END OF THE SKEIN - DO NOT CARRY THE WHITE YARN), K1 Placid Pink*
*-* = "base row"
Repeat base row 12 times.
**
Working exclusively with white, *K1, K2tog 5 times, K2.* Pick up the unworked white strand and work * to * again, then K7. Pick up the first white strand and K7. *With pink, K in front and back of next five stitches, K1 pink, K1 white, repeat from * once more.
K base row 13 times.
Repeat from ** until work measures 30". Lightly stuff the intestine with polyfil. Switch to size 8 needles and knit another 15 inches, ending before a white row. Lightly stuff this section of intestine.

Appendix:

Knit 5 stitches past a white stitch. Cut yarn, leaving about a 6' tail and thread onto a tapestry needle. Fold the tube so that the yarn tail comes out the right edge and the dpns are parallel. Weave together ten stitches (five from the needle in front and five from the needle in back). Knit the next two stitches on the front needle (one of these should be the white stitch), then place them on a stitch holder. Place the next two stitches from the back needle (including the other white stitch) on the holder as well. Knit five stitches, then weave together the remaining stitches as before. Put the four stitches on a dpn and knit 1 1/2" of I-cord (still using the cut yarn tail). K2tog three times, thread the yarn end through the last loop, pull it tight and use the tapestry needle to thread the tail back through the I-cord, hiding it. Trim the yarn end.

Small Intestine:

Arrange the large intestine. The small intestine should arise from the back of the last segment. Using the bulky yellow-pink yarn, pick up six stitches onto the size 10.5 dpns in a circle at this location. Place 3 stitches on each of two dpns and knit across them with a third dpn (I find this faster than using four dpns for so few stitches). Knit until the small intestine measures 21 feet (yes, the human small intestine is 7 yards long. You don't have to make yours quite this long, trust me no one's going to measure, but you need at least 15 feet of innards for them to look authentic).

Stomach:
