Double Jacquard 2

The Passap Handbook for the Deco by Bernadette A Ernakovich was an excellent guide to exploring the qualities of changing lock settings on the hand, feel, look, and in shape alterations on the original design, a simple triangle, when using them. In knitting any fabric, distinctions need to be made between what is doable vs practical. Japanese machines are less tolerant than Passap for repeated functions on the same needles, and the numbers of stitches and of rows, if attempting to duplicate textures, often need to be adjusted or reduced. Some very interesting fabrics may be achieved by hand changing ribber carriage settings on the Brother KM, which are made far easier on the E 6000 because of  its collection of lock settings in conjunction with arrow keys on the back bed. I amended the “Passap” triangle to the smaller repeat below

punchcard (40 rows of punched repeat actually required for functional length)

This document DBJtest includes directions on using the design repeat as is, or separated for DBJ work by 2 different methods for both punchcard and electronics: color separations.  Swatch photos are below, this type of exercise shows how the resulting fabric may share a single design, but is changed sometimes surprisingly by changes in ribber settings

Because of recent changes in my life, I may be in the position of attempting to explain to some new knitters how DBJ “works”, and to offer them some suggestions on managing  the making of it. Since the machine I will be involved with is a Brother electronic specifically, I am gathering notes that are pertinent to that brand. I thought I would share some of my working notes here. The set below was gathered more than 2 decades ago, so I cannot add a specific bibliography, and information that may be gleaned from manuals is not included. This is the start of an ongoing series: 1.some DBJ rules for 2 color work, Brother machines, some adjustments need be made for more colors or for use on other brand KMs

knit slowly, watching edge stitches to ensure that they are knitting off properly. If they are not, hang the side weights on the work, and move them up every 20-30 rows

clear the end stitches on every row, be especially watchful in wide pieces, failure to do so may cause mis patterning or dropped stitches at edges

listen for the click when changing colors. On brother machines the carriage must be  taken far enough to the left for the click to occur, lining up the connecting plate for the yarn change. If color is changed without going far enough, you may either knit with the same yarn or no yarn

thread all four yarn holders, then if the wrong button is pressed you will only knit a row in the wrong color instead of dropping your work to the floor

check your yarn change before you knit each row for correct color or the possibility of 2 yarns traveling together

weigh the work evenly

be certain selection row is in correct direction (with pattern locked on punchcard), or you may end up with stripes rather than a pattern design

if you need to stop work , leave with carriage on right, it makes it easier to identify which color was last used in your sequence

do not use fully fashioned decreases as this affects the pattern near the edge stitches

reduce weights to correspond tho the number of needles in use when decreasing

work multiple decreases ie at underarms with carriage on the right, this way both sides may be shaped at once using the main yarn on right, the next color on left, thus avoiding long floats

if the design is not an all over one, continue in Jacquard for remainder of fabric, using a repeat that has 2 rows marked/punched, 2 rows un marked/punched throughout

ribs in single strands of garment yarn may be foo soft or wide, for 1X1 ribs try adding an extra strand of yarn. When completed, pick up the heel of the adjacent stitches to fill in empty needles, and knit 2 circular rows before continuing in jacquard

2X2 ribs are better suited to single strands of yarn; at the top of the rib bring the empty needles into work, rack to the left and knit 2 circular rows, rack to the right and continue in jacquard

full needle ribs are usually wider than jacquard, as an alternative the piece could be started on waste knitting, and rehung on fewer stitches, then in turn knitting the rib

the lili buttons represent an every other needle set up, so an even number of needles is required; the needle position indicators on the  ribber tape and the corresponding space between them help track pairs/ even numbers of needles in work

racking handle on P: the knit and purl needles are point to point, directly opposite each other, on H the purl needles are are halfway between each pair of needles on the opposite bed, and the latter is most often the basic needle arrangement for doouble jacquard; check needle alignment before knitting planned fabric to avoid needle damage, etc

vertical striper backing on brother kms is possible, but needs a bit of added manipulation and its own specific directions for needle set up

for thicker fabrics the needle arrangement on ribber may be for 1X1 rib, 1X3, or other configuration, pitch on P. The larger the number of needles on either bed, the closer the tension on that bed to the tension suitable for that yarn in plain stocking stitch. In this instance, the ribber tension is tightened up by one or 2 numbers. If the ribber needles are in ever groups ie 2X2, 4X4, 4X2, etc, then the lili setting may be used. This sometimes helps if the effect on the knit side tend to show noticeable vertical lines along the sides/length of the stitches created on the ribber.

Knit topological shapes

It is possible to construct topological shape via knitting. In HK this may be done on circulars. One out of many tutorials may be found here, and the mathematical knitting is a very good, extensive resource.

A recent forum post on knitting such shapes on the machine led me to dig out an old sample of mine knit with brass wire and holding on the km flatbed; since I never actually determined an end use, the donut hole inner seam was never joined.
in this view the piece is about 3 inches in height, and 8 inches across

Photos of my work

I had a long interval of time when I did not record any of my work with photographs. I have slides from my student days, but even  as I first sold my work I have always leaned toward one of a kind or limited edition items. My knitting history began back in the days of what are now out of date cameras, and professional photographers were too expensive for the volume of inventory created and expected sales, so I often opted for no photos. At some point I accepted my own limited skill in photography, and began to record items as they were being made for record keeping more so than any other reason. With the start of  my presence online I graduated from one camera to another and then to instant iPhone gratification, my photography collection grew, and became simply what it was. I recently “went pro” on flickr, and have been adding photos of some of my early work, and of my little bit of publishing patterns in Studio by White Design magazine in the early 1990s, which may be found in my “memory lane” set on flickr. I have great admiration for anyone that publishes patterns and the work involved in doing so, though perhaps shared platforms for documents being as common as they are now might make the process easier.

Studio by White Design in its short lived glossy color format was the company publication in the early 90s. The constraints for any patterns were that they needed to promote an accessory, had to be in the requested assigned category ie men, children, etc, and help the reader learn a technique. At times yarn companies and publisher would have relationships, and kits for executing the patterns were offered. I designed 3 sweaters for them, these are the accompanying magazine shots

FW 93: 2col tuck mosaic for both punchcard and electronic

FW 94: an intarsia sweater using striping, FI, pin tucks, eyelets and rolled edges all on single bed

Summer 95 a slip stitch sweater

Entrelac pretender 3

A larger cousin is in the works using slip stitch setting combined with holding to create an “entrelac like” fabric. It helps to be familiar with both techniques before attempting this fabric. I am not providing specific directions for knitting, but the repeats are correct and tested, and are intended as a springboard, not a “how to”.

the related punchcard repeats

the needle bed markings to help track motif placement (red for red card, which correspond to needle tape factory markings for repeats, black marks are halfway in between for the opposing shapes)

As each set of repeats for each card is completed the punchcards are exchanged. KC direction is marked on them, with knitting beginning on the opposite side. I found the fabric more manageable when I completed and began each design sequence and color change by beginning and ending with an all knit row in that color. The bottom of the swatch shows the difference in side edges if half repeats are not planned for. If this were a production item it would actually be possible to work out the repeat on enough cards so they could be used as a continuous roll rather than having to so frequently reinsert and re join them. This sample was knit in Jaggerspun wool, and since wool has memory, the resulting 3D texture remains after steaming, resulting in a noticeable difference from the previously knit acrylic swatches.

this is the purl side with obvious changes in width and some problem yarn feeding

and here is the knit side

there is a large number of rows between repeats, so there will be yarn ends that need to be dealt with, but they are far fewer than in knitting individual motifs, and only at sides of the piece.
