Shawl Geometry: Shallower Triangle

This is the sixth post (out of 16) in a series about different shawl shapes and how to knit them. The introduction post, which lays out the game plan can be found… thisaway.

 

The Shallower Triangle Top Down

To work the shallower triangle top down, you work one increase every row at each edge, and a pair of two increases along the center back spine every third row.
(Thanks for figuring this one out and for sharing it Dana!)

Shallow Triangle

To work this shawl top down in garter stitch:
CO 5 sts.
R1: K1, m1, k1, m1, pm, k1, pm, m1, k1, m1, k1.
R2: K1, m1, k to last st, m1, k1.
R3: K1, m1, k to last st, m1, k1.
R4: K1, m1, k to marker, m1, sm, k1, sm, m1, k to last st, m1, k1.
Repeat R2-4.
To work this shawl top down in stockinette:
CO 5 sts.
R1 (RS): K1, m1, k1, m1, pm, k1, pm, m1, k1, m1, k1.
R2 (WS): P1, m1, p to last st, m1, p1.
R3: K1, m1, k to last st, m1, k1.
R4: P1, m1, p to marker, m1, sm, p1, sm, m1, p to last st, m1, p1.
R5: K1, m1, k to last st, m1, k1.
R6: P1, m1, p to last st, m1, p1.
R7: K1, m1, k to marker, m1, sm, k1, sm, m1, k to last st, m1, k1.
Repeat R2-7.

The Shallower Triangle Bottom Up

To work this shawl bottom up, first figure out how many hem stitches to cast on. Determine your gauge and how deep you want your shawl to be along the center back spine.

1. [depth of shawl] / 2 = [Z]
2. [Z] x [1.732] = [magic number]
3. [magic number] x [rows per inch] = [number of rows total]
4. [number of rows to work] / [3 rows in a decrease repeat] = [number of decrease repeats]
5. [number of decrease repeats] x [8 sts decreased per decrease repeat] = [number of stitches decreased] Make this number a whole number that is divisible by 8.
6. [number of stitches decreased] + [5 bind off stitches] = [number of stitch to cast on]

Shallow Triangle Bottom Up

Then if you’re working in garter stitch:
Cast on your hem stitches, marking the center stitch with a marker on either side.
R1: Ssk, k to 2 sts before marker, ssk, sm, k1, sm, k2tog, k to last 2 sts, k2tog.
R2: Ssk, k to last 2 sts, k2tog.
R3: Ssk, k to last 2 sts, k2tog.
Repeat R1-3. Until you have 5sts left.
Bind off.

If you’re working in stockinette:
Cast on your hem stitches, marking the center stitch with a marker on either side.
R1: Ssk, k to 2 sts before marker, ssk, sm, k1, sm, k2tog, k to last 2 sts, k2tog.
R2: P2tog, p to last 2 sts, p2togtbl.
R3: Ssk, k to last 2 sts, k2tog.
R4: P2tog, p to 2 sts before marker, p2tog, sm, k1, sm, p2togtbl, p to last 2 sts, p2togtbl.
R5: Ssk, k to last 2 sts, k2tog.
R6: P2tog, p to last 2 sts, p2togtbl.
Repeat R1-6. Until you have 5sts left.
Bind off.

This variation creates a triangle that is shallower then the traditional triangular shawl, this makes it a bit easier to wear because you don’t need to make a blanket to make your shawl wide enough to warp around your shoulders comfortably.
