Valley Yarns #287 Birch Bark Scarf

Valley Yarns Birch Bark Scarf: Woven Bamboo Design

What Is Being Made

The Valley Yarns Birch Bark Scarf is a woven accessory designed by Cynthia Cox, featuring an elegant color combination inspired by natural textures. The finished scarf measures 9.25 inches wide by 64 inches long (excluding fringe), making it a versatile piece suitable for various styling occasions. The design draws inspiration from the subdued tones found in birch tree bark, translated into a sophisticated weaving pattern that combines Natural and Taupe colorways for a timeless aesthetic.

Weaving Structure and Techniques

This pattern utilizes a twill variation weave structure, a technique that creates diagonal lines and adds visual interest to the fabric. The design employs striped techniques to achieve its distinctive appearance, with color changes between the warp and weft creating crisp pattern definition once the piece is removed from the loom. The pattern is created using a 4-shaft loom, which allows for the interlocking of threads in the twill variation sequence.

A key characteristic of this weaving project is its intentionally open, lace-like structure on the loom. The designer notes that bamboo fiber requires trust in its behavior during finishing—the generous sett (thread spacing) produces a beautiful drape that becomes apparent only after the scarf is completed and the fibers relax off the loom. This transformation is part of the appeal of working with bamboo yarn.

Yarn and Materials

The Birch Bark Scarf is woven entirely with Valley Yarns 5/2 Bamboo, a yarn composed of 100% rayon from bamboo fiber. This yarn is sold on 1.25-pound cones with a yardage of 2,100 yards per pound.

• Warp Yarn: Valley Yarns 5/2 Bamboo in Natural, requiring 450 yards
• Weft Yarn: Valley Yarns 5/2 Bamboo in Taupe, requiring 314 yards

The warp is wound at 3 yards in length with 148 ends, plus floating selvages on each side for finished edges.

Loom Setup and Technical Specifications

This pattern requires a 4-shaft loom with a minimum width of 14 inches. The equipment list includes 1 shuttle and 1 bobbin for the weaving process. The threading follows a specific threading draft included in the pattern, with 20 repeats of the draft sequence.

The sett (density of warp threads) is set at 12 ends per inch (epi) and 12 picks per inch (ppi). The designer notes that this sett is more open than the typical recommended range of 16-20 epi for 5/2 bamboo yarn, but this deliberate choice creates the desired lace-like appearance on the loom and contributes to the exceptional drape of the finished fabric. Maintaining the 12 ppi during weaving ensures crisp pattern definition and optimal fabric characteristics.

The width in the reed measures 12.5 inches, which accounts for the finished width of 9.25 inches after the fabric naturally draws in during weaving and finishing.

Finishing and Design Considerations

The pattern includes a treadling draft and tie-up configuration specific to the twill variation structure. Floating selvages (one on each side) are added during the dressing process to create finished edges. The designer recommends spreading the warp with scrap yarn picks and using spacers as needed to maintain consistent tension and structure during the weaving process.

The Birch Bark Scarf pattern is distributed by WEBS and is available as a downloadable PDF for personal use, allowing weavers to work at their own pace with detailed instructions and visual guides for successful completion of this elegant bamboo weaving project.
