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.

Mesh Yarns, Hairpin Lace, and Heirloom Sewing

Hairpin lace on the loom

Hairpin lace loops bound singly or in groups (top side)

Hairpin lace is a crochet technique in which long strips of fabric are created with long, even, loops on both sides of a central pair of stitches. Typically, the loops are crocheted together singly or in bunches, after which the strip is crocheted to other similar strips to create a full garment, though there are patterns in which the loops on adjacent strips are chained into each other (interwoven), or in which the crochet stitches are stabilized and the loops left free.
 


Heirloom sewing is a collection of techniques used to add lace and embroidery to special-occasion garments, often with Edwardian- or Armistice-Era design elements. Among these techniques are lace insertion, in which a strip of lace with unembellished edges is inserted into the body of a garment piece (see images here), and the underlying fabric cut away to create an element of airiness, and puffing strips, in which a long strip of fabric is gathered on both long sides, attached to lace insertion on both sides, and then inserted into a garment to create a dimensional effect (images). Several lace insertions, with or without puffing strips, may be sewn one to the other to create a broader trim known as a fancy band.

Hairpin lace, heirloom lace insertions, puffing strips, and fancy bands are similar in that they are narrow strips of material that can be combined to create a wider material which can be used either to create a garment or as decorative elements within a garment. Hairpin techniques used to edge and join Sashay Lengths of mesh yarn can be used in place of strips of hairpin lace, or in the design space of lace insertions or puffing strips, to create similar effects in knitted and crocheted garments. One pattern that uses mesh yarn in place of hairpin lace is Red Heart Yarn's Wrap and Go Shawl.

Splicing together two strips of Starbella

To splice together two strips of mesh lace Match your thread size to the threads used to make the mesh yarn (Starbella takes size 20 or 30 crochet cotton) Count the number of stitches between a thread's connections to its adjacent thread (A), and the number of stitches in which it is connected to that adjacent thread (B). For the sample of Starbella above, A = stitches and B = 2 stitches along Thread 1. Choose a steel hook size to create same number of chains/stitches per inch with crochet cotton. (In the example to the right, I used a number 12 hook and size 30 crochet cotton. I should have probably used a number 9 hook.) Chain 1/2 A, then connect to Strip 1 with B stitches. Chain 1/2 A, then connect to Strip 2 with B stitches. Repeat until you run out of length on the two strips. Detail

Interweaving two strips of Sashay To interweave two strips of yarn together Detail Pull Thread 1 of the first strip through Thread 1 of the second strip.  Insert the hook (or needle) through the next open space on Thread 1 of the second strip; pull through the loop on the hook (or needle). Insert the hook (or needle) through the next open space on Thread 1 of the first strip, pull through the loop on the hook (or needle) Repeat as long as necessary to create the required length of ruffle yarn.

Changing the Ruffle Width

The mesh structure of ruffle yarns allows us to play with the width of the ruffle — that is to say, how far it stands out from the body of the fabric. In sewing, a narrower ruffling strip makes a narrower ruffle, and that's pretty much the end of it. (Unless you're ruching the strip, which is the subject of another post.)

We can create a narrower ruffle in two ways:

1. We can work the first two, three, four, or more threads together into a thick working edge.
   

   Working the first, first two, first three, and first five threads of Sashay.

2. We can make the second, third, fourth, or middle thread as if it were the working edge, leaving Thread 1 to form a second, often shallower, double ruffle.

Ruching

Ruching is a pleating or ruffling technique of taking equal, measured stitches diagonally across a narrow piece of trim in a zig-zag pattern and gathering the fabric along the seam line, straightening out the seam. The result is equally-sized puffs of fabric on both sides of a central seam, each side offset from the other by half the length of the zig-zag.

Another method is to slip stitch along the ruching lines. This creates an equally measured path along which the yarn can be easily folded, creating two overlapping rows of petals.

Adding Your Own Edge Treatment

In addition to the embellishments that already exist on many ruffle yarns, you can add your own twist by crocheting, tatting, or using another edging technique to add color, depth, fill, or other design to your mesh yarns.

Adding crocheted edgings to Trendsetter Yarns' Flamenco.

For some, this may seem to be gilding the lily, but having two finished edges emphasizes a number of design options  —  such as double ruffles and mock hairpin lace.

Keep in mind include the size, weight, style, and fiber of your added edge. While the simple shell edges I've added above are in scale for Trendsetter Yarns' Flamenco, the wool blend fingering yarn (Fox Brand Velnette, a vintage crepe yarn from from my stash) is so heavy, comparatively, that it wants to collapse the mesh, and as a dry-clean only yarn, would shrink and full at a different rate than the mesh yarn were someone to stick it in the delicate cycle, ruining a finished garment.

More to scale is the simple single-crochet row of size 30 crochet cotton I added to the sample of Starbella Flash in the second photo. While I've not put enough trim on that yarn to be decorative, I wanted to emphasize the unembellished border for another technique I'll be demonstrating shortly.
