{"type":"firestarter.listing","listing":{"id":"lst_NPOXAA_Y","product_name":"Custom Inseam Chain Stitch Hem Service - 21oz to 25oz Heavyweight Brave Star Jean","category":"Selvage Denim","description":"ALL CUSTOMIZED PRODUCTS ARE  FINAL SALE AND ARE NON REFUNDABLE.\nEU CUSTOMERS:\nCustom hemmed jeans are final sale except where defective or incorrectly supplied.\nNOTE: A FULL INCH AND A HALF (1.5\") IS ADDED TO ALL HEAVYWEIGHT CUSTOM HEM SERVICE ORDERS TO ACCOMMODATE ANY POTENTIAL SHRINKAGE. IF YOU ORDER A 32\" HEM SERVICE YOU WILL RECIVE A 33.5\" INSEAM.\nIf you need your selvage denim hemmed to a custom inseam then look no further. There is only one way to chain stitch a selvedge denim hem and that's on a folder equipped Union Special 43200g. Why you ask? These machines create a desirable roping effect on the hem which is actually caused by a feed differential defect. What this means is that the fabric is metered through the folder (which feeds the hem to the needle) at a different speed than the feed dogs (on the bottom pulling the fabric) causing a push/pull effect on the hem which is what ultimately causes the roping effect. This roping effect is one of the characteristics that make vintage denim so desirable to collectors and the reason why these machines are so sought after now. The 43200g was first manufactured in 1939 and was phased out in the 80's. Because they were known for this mechanical defect a lot of them were abandoned, stripped for parts and exported to places such as North Africa and South East Asia. To find one in such good working condition as we have is truly rare.\n\nHemming will take an extra 7-10 business days for order processing \n\n","images":["https://cdn.shopify.com/s/files/1/0337/0573/products/2016-10-20_14.13.08-2.jpg?v=1564618666","https://cdn.shopify.com/s/files/1/0337/0573/products/20190723_SlimStraight_19oz_HatchAttack_Pants_Cuff_Mik.jpg?v=1564618666","https://cdn.shopify.com/s/files/1/0337/0573/products/43200g_small_a722fc81-c8bf-4000-bac5-696954d87cf8.jpg?v=1564618666"],"price":25,"currency":"USD","in_stock":true,"inventory_qty":169983,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:32.091Z"},"share_url":"https://firestarter.network/l/lst_NPOXAA_Y","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
