This Tutorial Will Explain What a Balanced Plied Yarn Is, and H
An HJS Studio Tutorial: To Chose or Not to Choose an Electric Spinner Introduction I've been spinning since March 1986, when I got started with a homemade drop spindle, some very coarse and ugly carded wool, and a little booklet about drop spinning—almost as low-tech as you can get. Today I'm the happy owner of an electric spinner, which I use almost exclusively. I still drop spin, especially with very fine, short fibers, and still use my Ashford Traveller when I won't be around electricity, but the espinner is my prime choice for all other spinning. This page is for those who are contemplating purchasing an espinner, those who can't understand why someone would use an espinner, and production spinners with speed on their minds. I wel- come specific questions; contact me any time if you think I can help. Reasons to get an espinner seem to fall into two main categories: Speed, and physical need. Speed I approached the purchase of an espinner from the speed point of view, and have learned a lot along the way about what speed really is on any spinning device. A brief diversion to explain what the ratio on a wheel is. It's essentially the number of times the flyer turns each time the drive wheel is turned one time. It's expressed so: 30:1 (read as "thirty to one") which means your flyer turned 30 times for one full turn of the drive wheel. Each turn of the flyer puts one twist into your fiber. -
4-H Crocheting Project Member Guide
4-H Crocheting Project Member Guide Crocheting is one of the oldest needlework arts. To crochet means to form yarn or thread into a fabric using a hook. Its name comes from the French word croche, meaning “hook.” The crochet hook was one of many tools first used to make delicate lace. As time went on, more stitches and designs came into being, and crocheting became a separate art. Crocheting appeals to many people because it can be used to make a variety of creations, such as scarves, caps, vests, sweaters, purses, belts, lace, doilies, tablecloths, afghans, pillow covers, and bedspreads. In the 4-H Crocheting Project, you can learn to: • Crochet articles for yourself and others • Select, use, and care for crocheting tools • Work and share with others in your club • Keep simple records of your project and activities The 4-H Crocheting project is divided into six phases. Skills to learn and suggested articles to make are on page 2. Your club leader will teach you how to do basic crochet stitches and help you find patterns to use as you learn. When you reach the advanced phases, you’ll need to choose patterns from a variety of pattern books, needlework books, and magazines. You can find these at newsstands, notions counters, fabric stores, or specialty shops that sell yarn and thread. If you want to show others what you learn in the Crocheting project, check with your leader about exhibiting articles at fairs or other community events. If you make an article to wear, you might like to model in your county 4-H fashion revue. -
Using Cotton Sliver Draft Force to Evaluate Textile Processing Efficiency, Part I
USING COTTON SLIVER DRAFT FORCE TO EVALUATE TEXTILE PROCESSING EFFICIENCY, PART I D. D. McAlister, III, J. D. Bargeron, L. C. Godbey ABSTRACT. Fiber bundles in sliver form more closely represent the fiber bundles commonly used in commercial testing. Therefore, this experiment focused on studying drafting force using untwisted fiber bundles (sliver) rather than twisted fiber bundles (roving) as had been previously studied. Four cottons of similar micronaire but different lengths were utilized for this experiment. Ring spun yarns of three different linear densities were produced from each cotton to cover the range of coarse to fine yarns commonly produced in a textile mill. Fiber quality, processing quality, and yarn quality were measured for each cotton in addition to finisher sliver drafting force. The analysis of the data indicates that short fiber content has the greatest impact on drafting force. In addition, it appears to be possible to determine processing waste and spinning efficiency levels through the determination of drafting force of sliver. Keywords.

Spinning Alpaca: Fiber from Huacaya Alpaca to Suri Alpaca (And Beyond)
presents A Guide to Spinning Alpaca: Fiber from Huacaya Alpaca to Suri Alpaca (and beyond) ©F+W Media, Inc. ■ All rights reserved ■ F+W Media grants permission for any or all pages in this issue to be copied for personal use Spin.Off ■ spinningdaily.com ■ 1 oft, long, and available in a range of beautiful natural colors, alpaca can be a joy to spin. That is, if you know what makes it different from the sheep’s wool most spinners start with. It is Sa long fiber with no crimp, so it doesn’t stretch and bounce the way wool does. Sheep’s wool also contains a lot of lanolin (grease) and most spinners like to scour the wool to remove excess lanolin before they spin it. Alpaca doesn’t have the same grease content, so it can be spun raw (or unwashed) pretty easily, though it may contain a lot of dust or vegetable matter. Alpaca fiber also takes dye beautifully—you’ll find that the colors will be a little more muted than they would be on most sheep’s wool because the fiber is not lustrous. Because alpaca fiber doesn’t have crimp of wool, the yarn requires more twist to stay together as well as hold its shape over time. If you spin a softly spun, thick yarn, and then knit a heavy sweater, the garment is likely to grow over time as the fiber stretches. I hadn’t much experience spinning alpaca until I started volunteering at a school with a spinning program and two alpacas on the working farm that is part of the campus. -

It was the fall of 2013. Some of you may not have even owned your business in the yarn industry yet, while others of you had been at it for well over 20 years. Some of you had not yet become parents; others were close to becoming empty nesters. A lot can change in five years, but of course, a lot can stay the same. Five years ago, Yarn Market News made a change. Because of dwindling advertising dollars, we announced that we would be publishing three issues a year instead of five. And this issue marks our first all-digital issue, born out of both a desire to go green and to help the magazine’s struggling bottom line. -

An HJS Studio Tutorial: Spinning Silk Caps I am proud to welcome Carol Weymar, a self-taught spinner and dyer of silk caps. I was much struck by the beauty of her work when I saw her website, so I asked her to write an ar- ticle, as silk is something I have no skill spinning. I hope you'll be as inspired by her expla- nation as I was! About Silk Caps Silk caps are made from cultivated cocoons that have been degummed and stretched over a frame shaped like a bell. They consist of a number of extremely thin layers; each layer is one cocoon. A cap "bell" is roughly two dozen caps, weighing about a pound altogether, which are fastened together at their tops and covered by one large cap whose edges are drawn out and tied together at the bottom to make a neat bundle. Cap silk is one of the most underrated types of silk available to the handspinner. It has its quirks, certainly, but mastering this form of silk is well worth your effort. It displays the beau- tiful luster of all its sister silks, but has the advantage of being a nearly continuous fiber. This means you can spin it to a very fine thread and it will be strong. It makes an excellent warp. It is very versatile; you can spin it into beautiful yarns, you can draw it into fine roving and knit or embroider with it in its unspun form, and you can blend it with other fibers to add bright color and gleaming highlights. -
Reflecting Noble Luxury and Refinement, New Lightweight Wool Materials Are of Key Interest to Designers, Retailers and Bespoke Tailors
Reflecting noble luxury and refinement, new lightweight wool materials are of key interest to designers, retailers and bespoke tailors. Beyond demanding perfected fits and wool’s signature aesthetic, discerning consumers expect emotional, sensorial tactility in garments. Responding to luxury market demands, leading Italian and English spinners and weavers are introducing exclusive fine-micron yarns and fabrics, derived from rare Australian merino. Stylesight explores Baruffa Group’s finest wool yarns for first-class sweater knits, cut-and-sew jersey, and wovens. Vogue Australia December 2012 / Elizabeth Debicki in wool, on location at Haddon Rig, a Merino wool farm in New South Wales. With seductive, magnetic charm, lighter weight but often still densely constructed wovens and knits are key on men and women's runways and at textile trade shows. Wool—traditionally a winter fiber—evolves with cutting-edge superfine qualities from 150s and 180s up to 250s. Offering noble refinement and unique trans-seasonal possibilities, wool moves beyond its pastime connotations.
