Santa Fe, New Mexico 2015 Proceedings Simply String Art Carol Beard, Central Michigan University, USA Key Words: String art, surface design Purpose: Simply String Art was inspired by an art piece at the Saint Louis Art Museum. I was intrigued by a painting where the artist had created a three dimensional effect with a string art application over highlighted areas of his painting. I wanted to apply this visual element to the surface of fabric used in apparel construction. The purpose of this piece was to explore string art as unique artistic interpretation for a surface design element. I have long been interested in intricate details that draw the eye and take something seemingly simple to the realm of elegance. Process: The design process began with a research of string art and its many interpretations. -
+1. Introduction 2. Cyrillic Letter Rumanian Yn
MAIN.HTM 10/13/2006 06:42 PM +1. INTRODUCTION These are comments to "Additional Cyrillic Characters In Unicode: A Preliminary Proposal". I'm examining each section of that document, as well as adding some extra notes (marked "+" in titles). Below I use standard Russian Cyrillic characters; please be sure that you have appropriate fonts installed. If everything is OK, the following two lines must look similarly (encoding CP-1251): (sample Cyrillic letters) АабВЕеЗКкМНОопРрСсТуХхЧЬ (Latin letters and digits) Aa6BEe3KkMHOonPpCcTyXx4b 2. CYRILLIC LETTER RUMANIAN YN In the late Cyrillic semi-uncial Rumanian/Moldavian editions, the shape of YN was very similar to inverted PSI, see the following sample from the Ноул Тестамент (New Testament) of 1818, Neamt/Нямец, folio 542 v.: file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 1 of 28 MAIN.HTM 10/13/2006 06:42 PM Here you can see YN and PSI in both upper- and lowercase forms. Note that the upper part of YN is not a sharp arrowhead, but something horizontally cut even with kind of serif (in the uppercase form). Thus, the shape of the letter in modern-style fonts (like Times or Arial) may look somewhat similar to Cyrillic "Л"/"л" with the central vertical stem looking like in lowercase "ф" drawn from the middle of upper horizontal line downwards, with regular serif at the bottom (horizontal, not slanted): Compare also with the proposed shape of PSI (Section 36). 3. CYRILLIC LETTER IOTIFIED A file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 2 of 28 MAIN.HTM 10/13/2006 06:42 PM I support the idea that "IA" must be separated from "Я". -

Radial Weavings
Radial Weavings Mandalas are a form of art that uses radial symmetry and geometric shape. This work, Mandala Cosmic Tapestry in the 9th Roving Moon Up-Close, features complex crocheted patterns, colors, and textures. The artist, Xenobia Bailey is known for their textile works, especially crocheted mandalas. Bailey famously draws inspiration from funk music and Native American, African, Hindu, and Buddhist cultures when creating her work. Experiment with radial symmetry and textile techniques to create a radial weaving. Supplies Needed: Xenobia Bailey (American, born 1955) Mv:#9 (Mandala Cosmic Tapestry in the 9th Roving Moon Up-Close) from • Cardboard or paper plate the series Paradise Under Reconstruction in the Aesthetic of Funk, Phase II, 1999, Crochet, acrylic and cotton yarn, • A circle tracer or compass beads and cowrie shell. Purchase: The Reverend and Mrs. • Yarn, string or fabric scraps Van S. Merle-Smith, Jr. Endowment Fund, 2000. • Scissors (2000.17.2) Follow these steps to make your radial weaving: Step 1: Trace and cut out a cardboard circle. You can also use a paper plate or paper bowl. This will be your loom. Step 2: Use your scissors to make an odd number of cuts into the edge of your loom. They should be evenly spaced out, like slices of pizza. Your cuts should be about an inch long. Step 3: Tie a knot at the end of a long piece of string. Slide it through the back of one of the cuts in your cardboard. Thread your loom by running the long piece of yarn through all of the cuts in the loom. -
Bath Time Travellers Weaving
Bath Time Travellers Weaving Did you know? The Romans used wool, linen, cotton and sometimes silk for their clothing. Before the use of spinning wheels, spinning was carried out using a spindle and a whorl. The spindle or rod usually had a bump on which the whorl was fitted. The majority of the whorls were made of stone, lead or recycled pots. A wisp of prepared wool was twisted around the spindle, which was then spun and allowed to drop. The whorl acts to keep the spindle twisting and the weight stretches the fibres. By doing this, the fibres were extended and twisted into yarn. Weaving was probably invented much later than spinning around 6000 BC in West Asia. By Roman times weaving was usually done on upright looms. None of these have survived but fortunately we have pictures drawn at the time to show us what they looked like. A weaver who stood at a vertical loom could weave cloth of a greater width than was possible sitting down. This was important as a full sized toga could measure as much as 4-5 metres in length and 2.5 metres wide! Once the cloth had been produced it was soaked in decayed urine to remove the grease and make it ready for dying. Dyes came from natural materials. Most dyes came from sources near to where the Romans settled. The colours you wore in Roman times told people about you. If you were rich you could get rarer dyes with brighter colours from overseas.

Old Cyrillic in Unicode*
Old Cyrillic in Unicode* Ivan A Derzhanski Institute for Mathematics and Computer Science, Bulgarian Academy of Sciences [email protected] The current version of the Unicode Standard acknowledges the existence of a pre- modern version of the Cyrillic script, but its support thereof is limited to assigning code points to several obsolete letters. Meanwhile mediæval Cyrillic manuscripts and some early printed books feature a plethora of letter shapes, ligatures, diacritic and punctuation marks that want proper representation. (In addition, contemporary editions of mediæval texts employ a variety of annotation signs.) As generally with scripts that predate printing, an obvious problem is the abundance of functional, chronological, regional and decorative variant shapes, the precise details of whose distribution are often unknown. The present contents of the block will need to be interpreted with Old Cyrillic in mind, and decisions to be made as to which remaining characters should be implemented via Unicode’s mechanism of variation selection, as ligatures in the typeface, or as code points in the Private space or the standard Cyrillic block. I discuss the initial stage of this work. The Unicode Standard (Unicode 4.0.1) makes a controversial statement: The historical form of the Cyrillic alphabet is treated as a font style variation of modern Cyrillic because the historical forms are relatively close to the modern appearance, and because some of them are still in modern use in languages other than Russian (for example, U+0406 “I” CYRILLIC CAPITAL LETTER I is used in modern Ukrainian and Byelorussian). Some of the letters in this range were used in modern typefaces in Russian and Bulgarian. -

The Arrow Shafts Is Pseudosasa Japonica Or Commonly Called Japanese Arrow Bamboo
The Japanese Arrow By Godai Katsunaga Intorduction The Ya, or arrow of Japan and was between 34 and 38 inches in length, made of fire hardened bamboo shafts and had a steel arrow head., During this period and earlier arrows used in combat were often marked to identify who owned them, this allowed samurai to get the proper credit for killing an opponent. Period Construction The bamboo used for the arrow shafts is Pseudosasa japonica or commonly called Japanese arrow bamboo. This bamboo grows in slender culms that are packed tightly together, forming a dense hedge, with large, dark green foliage. It is a tough and versatile bamboo that will thrive in shade and in sun while growing to about 15 foot tall and was common throughout Japan. Farmers and other workers harvested the bamboo in the early winter when the plants saps were down. To get the required diameter need to make arrows the plants that were between two and three years in age were preferred. After harvesting, the best bamboo was hand selected and ideally stored for about a year for drying, allowing most of the moisture in the plant material to evaporate. Preparation of each shaft included having the nodes shaved off and then softening the shaft by placing it in hot sand prior to straightening it by hand. After the shafts were straightened, they were exposed to high heat to remove any remaining moisture and harden the natural sugars, creating a stronger bond of the natural fibers; this was known as fire hardening. Fletching was done with hawk, eagle, crane or pheasant tail feathers and could be either three or four flights depending on the arrow head that would be mounted.
