HQ High Speed Sharp Pt 12 MR QM13250-2 Longarm Needles ^

Choose size 12 needles for use with finer threads and fabrics, such as silk. Recommended for use with the Handi Quilter machine or when using the HQ Micro Handles for micro-quilting or when quilting on the Handiqulter Avante, Forte, Infinity. 

The Groz-Beckert MR needle style is specifically made for multi-directional use, which is exactly what longarm machines need.

Multi-directional design means more accurate stitching while moving the machine in any direction. The MR needle style has maximum flexibility and bending to help reduce needle breaks and a deep scarf to mitigate skipped stitches
