One is to keep the warp threads under tension by fastening them to the front and back (or top and bottom) of the loom. The other is to provide a way for the weft to be woven over and under the warp threads. When people discovered techniques for lifting multiple warp threads, creating a shed through which the weft can pass, they greatly increased the speed of weaving. People all over the world have developed different approaches to this simple concept; there are hundreds of examples of looms all over the world that date back thousands of years.\"\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003cp\u003eTo get information or class materials for this project: Please call (800) 338-9415 Mon-Fri 9-5 or email orders@harrisville.live\u003c\/p\u003e","brand":"Harrisville Designs","offers":[{"title":"Default","offer_id":42386649940132,"sku":"B518L9","price":7.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/2835\/8820\/products\/B518L9_2__11294.1408474917.1280.1280.jpg?v=1656346771","url":"https:\/\/harrisville.live\/products\/woolworks-curriculum-guide-grades-3-8-lesson-9-rigid-heddle","provider":"Harrisville Designs, Inc.","version":"1.0","type":"link"}
