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.

The End of the Yarn

There are two places in our work in which we come to the end of the yarn: when we are about to finish a skein in the middle of our work (and need to graft in more yarn to continue), or when we come to the end of our work and need to secure the final stitches.

Because of its bulk, the ends of a ball of ruffle yarn cannot be woven into the work the same way we work in the ends of traditional yarns.

Adding More Yarn

We've come to the end of our yarn

Overlay the old and new yarns
(contrast used to demonstrate technique)

Work the two yarns as one until the old yarn runs out

When adding more yarn, overlap the last three or four loops of the ball you are about to finish with the first three loops of the  new ball. Work the loops of both balls together, the same way you did with the folded-over loops at the start of  your work.

Finishing Your Work

With a Pulled-Through End (Ribbon Yarns, Worked As Yarn)

As you approach your last several stitches, count out the number of loops you will need to complete those stitches, plus an additional four loops. 

When you get to the end of your work, pull the remaining yarn through the last loop.

Pull to tighten the last stitch and secure the tail.

If the stitch will not tighten (which is typical for ruffle yarns), you will need to use sewing thread to secure the tail to the back of the work.

With a Sewn-In End

As you approach your last several stitches, count out the number of loops you will need to complete those stitches, plus an additional four loops. 

Cut the yarn along its width. 

Fold back the last four loops of the yarn, the same way you did with the first two loops when starting your work.

Work as usual, binding off (knitting) or crocheting your final stitches.

At the end, you should have a single loop of doubled yarn on your hook or needle. 

Take a needle and sewing thread, and sew this loop, either to the first two unworked threads of the yarn's edge, or to the previous two or three stitches of your work.

With a Knotted End (Mesh Yarns Only)

As you approach your last several stitches, count out the number of loops you will need to complete those stitches, plus an additional few loops. 

Cut the yarn along its width. 

Using only the four extra loops, cut the yarn along its length between the second and third threads, or between the highest-number worked thread and the thread beneath it..(If the yarn has many threads, you may want to make a parallel cut several threads down, to end up with two "strings" of about equal bulk, plus an embellished tail.)

At the end of the work, pull the working threads through the loop formed by the last stitch, leaving the cut part of the yarn behind.

Using the pulled-through yarn as one "string", and the remainder as a second "string", tie the two strings together using a square knot.

Trim the trailing ends, (and if appropriate, the embellished tail).

Binding Off

Because ruffle yarns are looser than standard yarns, a typical bind-off will appear very tight. While this is fine (even desirable) for The Scarf, it's less useful if you are using ruffle yarn for the fancy edge of a garment.

The method that seems to work for Sashay is:
(k1, slip the knit stitch back to the left needle),repeat, k2 tog, (slip the knit stitch back to the left needle, ((k1, slip the knit stitch back to the left needle), repeat, k2tog)), repeat until only one stitch remains.

This is basically knitting each stitch twice before knitting it together with the next stitch. As you can see from the photo, this leaves a pretty straight edge, though there's still a bit of tightness to it.

A variation of the more standard bind-off (k1, (sl1, pass knit stitch over sl st, knit slipped stitch), repeat) had me knitting the same Sashay stitch three times before binding off


A larger mesh, such as Starbella, may require knitting each stitch three or four times before binding it off by knitting it with (or slipping it over) the following stitch.

Design Note:

The curvature of the traditional bind-off (knit each stitch once before slipping it over the next stitch) can also be used to create a collar (see this section of Premier Yarns' Cascading Ruffles scarf) that lays flat on the neck and shoulders, an armhole trim, or other curved trimming.

Loops, Threads, Holes, and Spaces

The next thing we need to learn about ruffle yarns is how to refer to their internal structure.

When we look at ruffle yarns, we often look at them like we looked at sewing cards as children -- that is, we see specific holes into which we are supposed to insert our knitting needles and crochet hooks to make a scarf, shawl, or fancy trim.

Depending on who you talk to and the type of ruffle yarn you are talking about, these holes may be called "loops", "spaces", or "holes". Specifically, since fabric-based ruffle yarns have regular round holes punched in the manufacture of the yarn, the place-to-put-your-needle is very definitely a hole.

Most ruffle yarns are constructed several mutiple-ply threads that are connected to each other at evenly spaced intervals, alternating between the left-neighbor and right-neighbor threads.

For ease of navigation, I propose numbering these threads, starting from the working edge, like thus:

Sashay by Red Heart

Starbella Flash by Premier Yarns

Most patterns for working ruffle yarns ask the needleworker to work with the portions of the working edge between its connections to Thread 2, asking her to place her needle through the "loop" or "space" created between two adjacent connections.  

My next post will deal with describing the yarn across its width.

The Working Edge

Many ruffle yarns have two distinct edges: one which looks like most of the rest of the net, and one which is thicker, wider, more-closely woven, or embellished with metallic thread, chenille, "eyelash" or "fur" treatments, or pom-poms.

The typical method of working this yarn is to work along one edge off the yarn, leaving the rest free to form ruffles and swirls.

For the purposes of this workbook, the edge which looks like most of the net will be called the working edge, and the edge with the trim will be called the embellished edge.

On ruffle yarns without a distinct embellished edge, either edge can be considered the working edge, as long as that choice is kept consistent through the work*. The edge that is not worked is called the free edge. (For yarns with embellished edges, the terms "embellished edge" and "free edge" may be used interchangeably.)

Bernat Twist & Twirl

On ribbon yarns, the choice is quite simple: the edge with the loops is always the working edge; the edge with the bound fringe is always the embellished, or free, edge.
