Mock Croc, Scallop, or Shell-in-the-Yarn

Shell motifs is to crocheters as seed stitches are to knitters: a basic pattern of stitches that creates a small, textured motif in the finished work. They take little advanced knowledge and make the work go quickly. One of the most popular shell motifs today is the overlapping detached shell, also known as the crocodile stitch.


A similarly-scaled effect can be created in either knit or crochet by varying the number of threads we pick up each time we wrap the yarn over the hook or needle. The difference between this and ruching is that with the scallop stitch, we pick up all of the threads from the working edge through the indicated thread for the current wrap, rather than picking up only the thread of the current wrap. As I noted in a previous post, this will create a variable thickness in the working row; crocheters may need to use a larger hook to get the bulk of multiple working threads through the previous work. Conversely, knitters may need to use a smaller needle to manage working the multiple threads.

The basic method of working scallops is to pick up one additional thread on each stitch (or yarn-over) through the embellished edge, then one fewer thread on each stitch (or yarn-over) until only the working edge remains, and repeat.This works fine in a double or treble crochet and a wide mesh, in which the repeat may only take two or three stitches; it's a bit less obvious in knitting, where the repeat could take as many as twenty stitches.

One method of shortening this is to work with multiples of two, three, or more threads on each stitch.

I brought the pattern forward on the sample at right by working 1, 4, 7. all, 7, 4, 1 threads on an every third row pattern over 20 stitches. I brought all the scallops to the front of the work, and straight ruffles to the back, as follows: R1, 2: knit --start pattern-- R3: knit scallop row R4: knit R5: purl R6: purl scallop row R7: purl R8: knit --end pattern-- The scallops aren't precisely counterposed on this sample — I should have worked over 21 stitches to do perfect three-and-a-half pattern repeats: (1, 4, 7, all, 7, 4 for a six-stitch pattern) A deeper scallop might be achieved by skipping one or more spaces between each yarn-over.

In crochet, scallops can be sent to one side of the work using the ball front/ball back technique discussed in a previous post.

Front and Back of Work

It's easy to tell the inside from the outside of most knitted or crocheted garment pieces by the pattern of stitches: three-dimensional work such as cables and popcorn stitches are only apparent on one side of the finished work.

Up to this  point in this blog, I've only treated stitches that look the same on both sides of the cloth, with one exception: crocheting in the round.

When you crochet or knit [note: knit, not knit and purl] in the round, the bulk of the ruffle yarn remains on one side of the work, creating a tight ruffled texture on one side and the traditional appearance of knitting or crocheting on the other. When you work flat, the yarn  stays on the same side of the hook or needles, but each time you turn the work, you alternate working from the front and the back of the garment. This causes the ruffle to appear on both sides of the work, making it difficult to use for many garments other than The Scarf.

Knitting has a basic stitch that is different from the front and back of the work: stocking (stockinette) stitch. Alternating rows of knit and purl, the structure of the knit is seen on one side of the work, while a more condensed version of the garter stitch appears on the other side. With ruffle yarns, this usually-reverse side will contain all the fabric of the ribbon or mesh, while the knit side will appear as a loosely-worked traditional knit. Viewed from this side, the technique is called reverse stockinette stitch.

Crochet is another matter. In order to get a distinctive front and back of the work, we need to make sure that we are always feeding the yarn from what will become the outside of the finished fabric. Because this means switching the ball of yarn from in back of the work (when the ruffling is facing away from you) to the front of the work (between you and the hook, when the ruffling is facing towards you), I'm referring to it as "Ball Front/Ball Back". The following video describes the technique.
