Rhonda’s Favorite Quilting Needles

00favoritequiltingneedles

00rhonda-pierceSCHMETZ manufacturers 17 needle types so you have a great choice.  Sometimes technique will dictate  needle choice, other times, the thread or fabric.  I always like to say “it’s a dance between the needle, thread and fabric with YOU and your technique as the leader.”  If one needle is not performing to your expectations, don’t worry, needles don’t have feelings — change to a different needle type or size.  Here are my top four SCHMETZ needle choices for quilting:

• Microtex — For piecing and stippling in sizes 70/10 or 80/12.  The Microtex is my “must have” needle for sewing on batiks and for appliqué. Because this needle has a “very slim acute point” it wears out faster.  I can usually see an inconsistent stitch or hear a click when this needle is ready to be changed.   This needle easily creates a stitch of precision!

• Quilting — The taper of the needle point is more sever, so the sewing experience is a bit different.  Available in two sizes, I use the 75/11 for piecing and the larger size 90/14 for the actual
quilting.

• Topstitch — The extra long eye on this needle is especially helpful when working with heavier, multiple or even aged (poor quality) threads.  There is less friction on the thread passing through
the eye resulting in less shredding and breakage.  I mostly use size 90/14 for quilting.

• Universal — This work horse of a needle works with nearly all fabric types to create a stitch with integrity.  This needle has the widest assortment of sizes from the finest 60/8 to the largest
120/19.  Yes, I have more Universals in my stash than any other needle type.
