Shawl Geometry: 3/4 Square

This is the thirteenth 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.


3/4 Square Top Down

This variation on the traditional square is also kinda/sorta a variation on the top down triangle. Because squares are made up of triangles, and triangles are just squares cut in half.

This shawl is simply three quarters of a square. So, the instructions are the same as for the square with a slit, but with three repeats instead of four.

34 Square Cent Out

To work this shawl top down (center back to hem):
CO 9sts.
R1: P across.
R2: K1, [k1, yo, k1, yo, pm] 3x, k2.
R3: P across.
R4: K1, [k1, yo, k to next marker, yo, sm] 3x, k2.
R5: P across.
Repeat R4&5 to desired dimensions.
Bind off.


This shawl fits and drapes in a way that is very unique to its shape. It doesn’t hug the shoulders in the same way squares or circles with slits do, or in the same way semi-circular shawls do. However, it does sit nicely, because it’s “missing” that quarter of a square it sits on the shoulders in a very open manner.

3/4 Square Bottom Up

Determine your final gauge, and decide how wide you want your square to be.
Divide your desired width in half (this is how wide your shawl will be from hem to center).

1. [number of rows per inch] x [number of inches from hem to center] = [number of rows total]
2. [number of rows total] / 2 = [number of decrease rows] you divide by two because you decrease every other row
3. [number of decrease rows] x [8 stitches decreased per decrease row] = [number of stitches decreased] make sure this number is divisible by 8.
4. [number of stitches decreased] / 4 = [one quarter of the full square of stitches]
5. [one quarter of your stitches] x 3 = [three quarters of the full square of stitches] make sure this number is divisible by 6
6. [three quarters of the full square of stitches] + [9 bind off stitches] = [number of stitches to cast on]

Cast on and decrease 6 stitches, in two pairs of two and one stitch at either edge, spaced evenly, every other row, until you have 9 stitches left on your needles.

So if you CO 63 sts:
R1: P1, [p20, pm] 3x, p2.
R2: K1, [k1, ssk, k15, k2tog, sm] 3x, k2.
R3: P across.
R4: K1, [k1, ssk, k to 2 sts before marker, k2tog, sm] 3x, k2.
Repeat R3&4, until you have 15 sts on the needle.
R5: P across.
R6: K1, [k1, sk2p] 3x, k2.
Bind off.
