◆◆How to Use the Gathering Foot◆◆ ① Attach the gathering foot. ② Tighten the upper thread to the maximum. ③ Set the stitch length to the longest. ④ Always backstitch and sew a straight line. ※ Gathers will not form on thick or layered fabrics. No comments needed, instant purchase OK. We do not offer discounts on single items. Discounts are available for purchases of 2 or more items; please leave a comment. I have used this with my home sewing machines (Brother 1, Janome 3, Singer 1) without any problems. ◆ I do not own a home Jaguar sewing machine, so I cannot confirm compatibility. If you are concerned about compatibility, we recommend purchasing a genuine gathering foot from an authorized dealer. We do not accept returns or complaints if the item is unusable after a test sew.
