Use broad rounded open notches without teeth or tensioning features. Ask for yarn thickness and color count. Keep the gap adjustable and do not promise that a notch will grip every yarn type.","steps":[{"title":"Plan the color order","detail":"Sketch one labeled position per yarn color in the order used by the project. Space labels so they remain readable when tails lie across the board."},{"title":"Shape the parking edge","detail":"Cut shallow rounded notches along one edge and leave the opposite edge continuous. Keep the transitions broad rather than making narrow V-shaped wedges."},{"title":"Add removable labels","detail":"Create shallow label recesses or a separate paper-label channel. Keep text and recess edges away from the yarn-contact path."}],"checks":["Lay actual yarn tails across a paper layout and confirm the sequence is understandable from the working position.","Inspect each notch for a narrowing throat or pointed internal corner that could pinch fibers.","Plan a two-notch sample with the intended finish before assuming the yarn will park or release as desired."],"pitfall":"A V-shaped notch can wedge the yarn more tightly as it moves; use a measured open profile instead of an assumed grip.","scope":"An unprinted sorting aid for loose yarn ends, not a tension controller or a validated way to secure an active knitting project.","materialNotes":"Consider PLA or PETG after sampling the notch finish. The material choice does not establish snag resistance or compatibility with delicate fibers.","links":{"html":"https://partsforagents.com/vibe-cad/yarn-tail-parking-board","markdown":"https://partsforagents.com/vibe-cad/yarn-tail-parking-board/guide.md","json":"https://partsforagents.com/vibe-cad/yarn-tail-parking-board/guide.json","catalog":"https://partsforagents.com/vibe-cad/catalog.json","order":"https://partsforagents.com/for-humans?project=yarn-tail-parking-board#workspace","agent_handoff":"https://partsforagents.com/guides/cad-to-print#connect","full_mcp":"https://partsforagents.com/api/mcp","free_advice_mcp":"https://partsforagents.com/api/advice/mcp","tool_schemas":"https://partsforagents.com/tools.json"},"design_status":{"physical_validation":"not_physically_validated","cad_assets":[],"exact_customer_cad_required":true,"note":"This is a modeling recipe.
