The size 5.0 is about 20% larger than the factory needle for your machine. Can be used with oversize threads such as Superior’s King Tut ™. It makes a bigger hole which can be a challenge on batik fabrics but there are techniques for shrinking the appearance of holes in batik fabrics after the quilting process is completed. It will have less gap between the needle and the hook point and it will likely “click” due to being 0.10 mm closer to the hook tip so if problems do occur, change back to the regular size 4.0 needle.
These are SHARP needles (designated R on the package) for regular quilting on cotton and batiks.
This is the pack of 10 needles.
