Teaching Weaving Fundamentals

If someone asks "how do I start weaving?", respond with this decision path:

1. No loom yet? Recommend a rigid heddle loom (affordable, versatile, good for scarves/towels) or a simple frame loom (cheapest, good for sampling).
2. First project: Plain weave (tabby) dish towels or a scarf — forgiving, teaches core mechanics.
3. Core process to explain:
   • Warp the loom (put threads under tension)
   • Wind weft onto a shuttle or butterfly
   • Weave a "heading" with scrap yarn to even out spacing
   • Weave the pattern, beating each pick
   • Cut off, secure ends, wet-finish (wash + dry to let yarn "bloom")

Don't overload a beginner with loom taxonomy upfront — give them one loom recommendation and the 6-step process above.

When helping someone with a weaving question, triage first:

Progress:
- [ ] Identify the question type: concept/terminology, loom selection, process/how-to, or troubleshooting
- [ ] Match to the right section below
- [ ] Give the direct answer first, then relevant context
- [ ] Suggest a next resource (book, project, or technique) if appropriate

1. Terminology questions

Define the term in one sentence using plain language, then relate it to the weaving process (not just a dictionary definition). Example: don't just say "sett = ends per inch" — explain it affects fabric density and is chosen based on yarn and desired drape.

2. Loom selection questions

Ask (or infer) three things: budget, space, and project type (functional vs. decorative, narrow bands vs. wide cloth, tapestry vs. plain weave). Then recommend:

• Tight budget / portability: frame loom, pin loom, or inkle loom
• General purpose, moderate budget: rigid heddle loom
• Pictorial/tapestry work: vertical tapestry loom
• Complex patterns, long-term investment: 4-shaft floor or table loom (default recommendation — "you could weave for 100 years and never get bored with 4 shafts")
• Band/trim weaving: inkle loom or card (tablet) weaving

Only mention dobby, Jacquard, or drawlooms if the user is already working with multi-shaft looms and asks about automating complex pattern control.

3. Process/how-to questions

Walk through the universal weaving sequence, adapting detail to their loom type:

1. Warp the loom (wind warp, thread heddles, sley the reed if applicable)
2. Wind weft (butterflies for tapestry/narrow work, shuttles for wider work)
3. Weave heading in scrap yarn to equalize spacing
4. Weave the pattern per the draft/cartoon
5. Cut off fabric
6. Stabilize edges (machine stitch, serge, or knot warp ends)
7. Repair any flaws with a needle
8. Wet-finish (hand wash, line dry) to set the weave

4. Troubleshooting questions

Diagnose using this mapping:

Example 1: Input: "I'm a complete beginner and want to weave dish towels. What loom should I buy?" Output: "Start with a rigid heddle loom — it's affordable, beginner-friendly, and well-suited to towels. Use cotton for both warp (strong, smooth, non-stretchy) and weft (absorbent). A good first project is a plain-weave towel using a simple draft; weave a scrap-yarn heading first to even out your warp spacing before starting the towel itself. Wet-finish when done — wash and line-dry so the yarn blooms and the weave sets."

Example 2: Input: "My weaving has wavy edges, what's wrong?" Output: "That's likely a selvedge tension issue. When you throw your weft, avoid pulling it perfectly taut straight across — leave a slight angle/slack (bubble the weft) before beating, so the weft can bend around the edge warp threads without pulling them inward. Aim for about 10% draw-in as a baseline. If waviness is across the whole width rather than just the edges, it's a warp tension problem instead — check for consistent tension when you wound the warp on."

Example 3: Input: "What's the difference between a jack loom and a countermarch loom?" Output: "Both are treadle looms that create sheds (gaps for the shuttle) differently. A jack loom uses levers that push shafts up when you press a treadle — simpler, lighter touch, common for home looms. A countermarch loom connects each shaft to two sets of lamms, so pressing a treadle pulls some shafts down and pushes others up simultaneously — gives a cleaner, more even shed, especially useful for dense or wide warps, but requires more complex tie-up."
