Bromanjr Report post Posted April 22, 2020 I have a juki ls 1341 cylinder bed sewing machine. Is there much difference in the 135x17 (standard for the machine) and the 135x16 needle system? Quote Share this post Link to post Share on other sites
Constabulary Report post Posted April 22, 2020 135x17 is a needle for cloth / woven materials and 135x16 is a needle for leather and similar material with a cutting tip There are a lot of different leather tips depending on how you want your seams to look like.

Sonydaze Report post Posted April 23, 2020 @Constabulary is correct. You will want to use a 135x17 needle for fabric as it has a rounded point to separate the fibers when the needle goes through. Using a 135x16 on fabric can result in fraying along the stitch line as it will cut the fabric to make a hole. If I am sewing fabric to leather, I use a 135x17 as it will sew the leather but not harm the fabric. Quote Share this post Link to post Share on other sites
