terrain hat generator

Knitting chart generator for the Terrain Hat; a hat that uses simplex noise as a stitch pattern.

simplex noise

Simplex noise is a clustered randomness algorithm. When translated into knits and purls it produces a stitch pattern with an organic texture.

The chart generator uses a new noise pattern each time the page is visited, creating a unique hat chart.

Unlike many traditional knitting patterns, there are no section repeats. The knitting chart shows the pattern in full: every knit and every purl. The lack of repeats does mean the pattern requires more focus when knitting, however, the upside is that any mistakes in following the pattern are barely noticeable.

charted knitting

The hat is knit in the round from the bottom up, using circular needles and/or DPNs. The chart is read from right to left, beginning at the bottom right corner. Basic decreases are used to shape the crown.

yarn weight

Aran / 10 ply (8 wpi)

gauge

18 stitches and 24 rows = 4 inches (10 cm) in stockinette

needles

16 inch US 6 (4.0 mm) circular needles
Set of US 6 (4.0 mm) DPNs

notions

Stitch markers
Tapestry needle

yardage

131 - 175 yards (120 - 160 m)

sizing

Adult medium = 96 stitches and 51 rows = 18.5 inches circumference (unstretched), 10 inches long (unfolded brim)

directions

Cast on 96 stitches and join for working in the round.

Round 1: (k1, p1) repeat to end of round.

Repeat round 1 until the brim measures 3.5 inches from the cast on edge. (for a folded brim)

Round 2: (k1, p1) repeat to end of round, placing a stitch marker after every 8 stitches.

Work from the chart, slipping stitch markers. Change to DPNs when there are too few stitches to fit on circular needles.

Break yarn, leaving an 8 inch tail. Using the tapestry needle, thread the tail through the remaining stitches and weave in ends.

abbreviations

DPNs - double pointed needles
k1 - knit stitch
k2tog - knit two stitches together
p1 - purl stitch
p2tog - purl two stitches together

notes

I recommend saving your pattern at several different row counts, just in case you decide you want to start the crown decreases a bit earlier or later.
