{"product_id":"wonderfil-serger-combo-pack-white","title":"Wonderfil Serger Combo Pack - White","description":"\u003cp\u003eA serger needs two different threads doing two different jobs, and this pack is simply both of them in one color. Four spools: two of SoftLoc™ Tex 35 wooly polyester for the loopers, two of Designer™ 40wt all-purpose polyester for the needle.\u003c\/p\u003e\u003cp\u003eSoftLoc is the fluffy one. It spreads out to fill an edge, which is what makes a rolled hem look solid instead of gappy, and it's soft enough to sit against skin on knitwear. Designer is the workhorse — 40wt general-purpose polyester rated to 50 lb per inch of seam strength, so it holds a garment together and runs clean at serger speed.\u003c\/p\u003e\u003cp\u003eBuying them matched saves the usual annoyance of hunting down a wooly poly that actually agrees with your needle thread.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhite\u003c\/strong\u003e is the default for light fabrics, and the one most people run out of first.\u003c\/p\u003e\u003ch3\u003eDetails\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 4 spools — 2 × SoftLoc™ Tex 35 wooly polyester, 2 × Designer™ 40wt all-purpose polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColors:\u003c\/strong\u003e matched across all four spools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoftLoc goes in:\u003c\/strong\u003e upper and lower loopers — rolled hems, decorative edging on medium to heavy knits and wovens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigner goes in:\u003c\/strong\u003e the needle, loopers, garment construction and general sewing; also fine on a domestic machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeam strength:\u003c\/strong\u003e up to 50 lb per inch (Designer)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wonderfil Threads","offers":[{"title":"Default Title","offer_id":48079205040293,"sku":"SCP-WH","price":17.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0442\/7871\/0437\/files\/SCP-WH.jpg?v=1785475146","url":"https:\/\/redrockthreads.com\/products\/wonderfil-serger-combo-pack-white","provider":"Red Rock Threads","version":"1.0","type":"link"}
