It yields soft greys, beige, or pink-tinted neutrals when used as a dye and builds excellent colourfastness when used as a tannin base. Made from the dried leaves and fruit of the sumac plant, this powder provides smooth, consistent coverage with a mild, earthy tone — a true cornerstone in sustainable natural dyeing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003cbr\u003eSumac bridges beauty and practicality — it’s both a dye and a mordanting powerhouse. As a tannin source, it rivals gallnut and myrobalan but with a distinct soft hue that complements warm palettes. Its sustainable origin and gentle performance make it ideal for conscious dyers seeking natural alternatives to chemical mordants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePre-treating cellulose fibres for improved dye uptake.\u003c\/li\u003e\n\u003cli\u003eProducing gentle neutral tones on wool or cotton.\u003c\/li\u003e\n\u003cli\u003eOver-dyeing with logwood or indigo for muted cool tones.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100% natural ground sumac leaves and fruit.\u003c\/li\u003e\n\u003cli\u003eHigh tannin content for strong fibre preparation.\u003c\/li\u003e\n\u003cli\u003eUse 10–15% WOF for mordanting or 30–50% as dye.\u003c\/li\u003e\n\u003cli\u003eProduces soft greys, taupes, and warm beige tones.\u003c\/li\u003e\n\u003cli\u003eWorks on cotton, linen, wool, and silk.\u003c\/li\u003e\n\u003cli\u003eEnhances brightness and durability of subsequent dyes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kraftkolour","offers":[{"title":"Default Title","offer_id":51912862531848,"sku":"L.ND.SUM","price":2.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2345\/3704\/files\/naturaldye-sumac1.jpg?v=1773421388","url":"https:\/\/winghamwoolwork.co.uk\/products\/natural-dye-sumac","provider":"Wingham Wool","version":"1.0","type":"link"}
