#Parameters:
min = 1 #needle number of left edge
max = 20 #needle number of right edge
rows = 20 #number of rows to knit
carrier = "3" #carrier name

# ---- set up initial loops and yarn carrier ----
#Bring in carrier:
K.ingripper(carrier)

#On Kniterate machines, carriers start on the left,
#so will start tucking onto needles left-to-right,
#and will be sure to tuck the leftmost needle in the first pass:
for n in range(min, max+1, 1):
	#tuck alternating needles, making sure to do the left edge:
	if (n - min) % 2 == 0:
		K.tuck("+", 'f' + str(n), carrier)
#now, moving right-to-left, tuck the needles that were not tucked on the first pass:
for n in range(max, min-1, -1):
	if (n - min) % 2 != 0:
		K.tuck("-", 'f' + str(n), carrier)

#knit three plain rows to allow cast-on stitches to relax:
# three isn't set in stone here -- it's just convenient
# for this example code to have the carrier end up on the right.
for n in range(min, max+1, 1):
	K.knit("+", 'f' + str(n), carrier)
for n in range(max, min-1, -1):
	K.knit("-", 'f' + str(n), carrier)
for n in range(min, max+1, 1):
	K.knit("+", 'f' + str(n), carrier)

# ---- single jersey sheet ----
#Create a single-jersey (all knits) sheet by alternating left- and right-going rows of knits:
for r in range(0, rows+1, 1):
	if r % 2 == 0:
		#left-going row:
		for n in range(max, min-1, -1):
			K.knit("-", 'f' + str(n), carrier)
	else:
		#right-going row:
		for n in range(min, max+1, 1):
			K.knit("+", 'f' + str(n), carrier)

# ---- take carrier out and drop remaining loops ----
#Send carrier back to its parking location:
K.outgripper(carrier)

#drop loops:
for n in range(min, max+1, 1):
	K.drop('f' + str(n))
