Crocheted Cross-Over Shell Stitch Step by Step Photo How-to
& Formula to Make Any Size Square


© 1999 S. Marshall
The cross-over shell is an interesting stitch ... and easier than it looks.

Use the formula below to make any size square or a full afghan.

Starting Chain: Multiple of 6, plus 4.

Directions
Note: In this pattern a shell = 3 dc, ch 1, 3 dc in same stitch and a half shell = 3 dc in same stitch.

Make starting chain of length desired.
Row 1: sc in 2nd ch from hook. sc in ea ch across.
Row 2: ch 4 (counts as first dc and ch 1), 3 dc in next sc, *ch 1, skip 2 sc, hdc in next sc, ch 1, skip 2 sc (3 dc, ch 1, 3 dc in next sc)* repeat * to * across to last 7 sts; ch 1, skip 2 sc, hdc in next sc, ch 1, skip 2 sc, 3 dc in next sc, ch 1, dc in last sc.
Row 3: ch2, *skip the 3 dc half shell,

Yarn over (yo) hook twice, insert hook in space between 1st and 2nd dc of next shell,

yo, draw yarn through stitch, * yo, draw yarn through 2 loops on hook *, repeat * to * twice. (1 treble made)

Work two more treble stitches in this same space between the 1st and 2nd dc of this half shell. This picture shows the third treble in progress.

ch 1, then working over the 3 tr just made, make a treble between 1st and 2nd dc of half shell just skipped; (Note that you need to draw up an unusually long first loop for each treble worked over the 3 tr just made.)

This shows one treble stitch completed. Work two more treble stitches in this same space between the 1st and 2nd dc of half shell just skipped,

sc in next ch 1 sp*.

Repeat * to * across until there is one cross-over left to do, then follow these directions: skip the 3 dc half shell, in sp between 1st and 2nd dc of next shell, make 3 tr; ch 1, then working over the 3 tr just made, make 3 tr between 1st and 2nd dc of half shell just skipped; sc in last dc.
Row 4: ch 3, 2 dc in same st, * ch 1, hdc in ch 1 sp in center of shell of previous row, ch 1; (3 dc, ch 1, 3 dc in sc of previous row)*, repeat * to * across until one cross-over shell remains; ch 1, hdc in ch 1 sp in center of shell of previous row, ch 1, 3 dc in last st.

Repeat rows 3 and 4 for pattern.

This sample is made with worsted weight yarn. With this thickness, the cross-over stitches are bulky but that's just what you want for a warm afghan!

With worsted weight yarn, with a size G crochet hook, a starting chain of 34 will make a piece that's 10" wide; a starting chain of 40 will make a piece that's 12" wide.

This sample is made with size 20 thread. A starting chain of ch 34, with a size 8 steel crochet hook makes a square that is 2 3/4" wide.

With sport weight yarn, with a size E crochet hook, a starting chain of 34 will make a piece that's 9" wide; a starting chain of 40 will make a piece that's 10 1/2" wide.

These examples give you a few ideas of the widths you'll get using different thicknesses of yarn or thread with different starting chains. Experiment with the starting chain formula of any multiple of 6, plus 4 to come up with the size you need for the item you'd like to make with this stitch.

Here are the directions again, all together:

Starting Chain: Multiple of 6, plus 4.

Directions
Make starting chain of length desired.
Row 1: sc in 2nd ch from hook. sc in ea ch across.
Row 2: ch 4 (counts as first dc and ch 1), 3 dc in next sc, *ch 1, skip 2 sc, hdc in next sc, ch 1, skip 2 sc (3 dc, ch 1, 3 dc in next sc)* repeat * to * across to last 7 sts; ch 1, skip 2 sc, hdc in next sc, ch 1, skip 2 sc, 3 dc in next sc, ch 1, dc in last sc.
Row 3: ch2, *skip the 3 dc half shell, in sp between 1st and 2nd dc of next shell, make 3 tr; ch 1, then working over the 3 tr just made, make 3 tr between 1st and 2nd dc of half shell just skipped; sc in next ch 1 sp*. Repeat * to * across until there is one cross-over left to do, then follow these directions: skip the 3 dc half shell, in sp between 1st and 2nd dc of next shell, make 3 tr; ch 1, then working over the 3 tr just made, make 3 tr between 1st and 2nd dc of half shell just skipped; sc in last dc.
Row 4: ch 3, 2 dc in same st, * ch 1, hdc in ch 1 sp in center of shell of previous row, ch 1; (3 dc, ch 1, 3 dc in sc of previous row)*, repeat * to * across until one cross-over shell remains; ch 1, hdc in ch 1 sp in center of shell of previous row, ch 1, 3 dc in last st.

Repeat rows 3 and 4 for pattern.
