*Round Shank Needles for Commercial Tin Lizzie 18", Queen Quilter 18", Ansley 26", and Artistic Quilter 18" Longarm Quilting Machines. Also works with Viking 18" Arm Quilter, and Pfaff 18" Longarm Quilter machines from Tin Lizzie, but not for any portable short or 9" mid-arm machines which take flat back home sewing machine needles.

"We use the Groz beckert 134 SAN 11 #18 needle it is titanium coated reduces friction and allows the needle to be cooler and is much harder for less needle deflection. It has a special design scarf which allows for better timing of the hook this allows us to bring the point of the hook closer to the needle this helps in forming a better loop which trans lates into less skipping of stitches. Regarding the shank of the needle it is larger than the body of the needle below the shank it will be thinner until the eye of the needle.The standard 134 and 135X7needles are much different."
