SCHMETZ Twin Needles When I started working with twin needles, my issue was, ‘What do the numbers represent? ’ Twin needles are usually labelled with two numbers, like this: 4.0/80 or 6.0/100 These numbers refer to: The distance between the two needles in millimeters The needle size/thickness (European sizing system) Example: 4.0/80 4.0 mm → The distance between the two needles (how wide the stitch will be) 80 → The thickness of the needle (European size, like a single needle size 80/12) SCHMETZ twin needles 4.0/80 and 6,0/100 Close-up example showing needle spacing in order: SCHMETZ #1794 Twin Needle Carded – 80/12 – 4.0mm, SCHMETZ #1776 Twin Needle Carded – 100/16 – 6.0mm and SCHMETZ #1734 Twin Needle Carded – 100/16 – 8.0mm SCHMETZ 80/12–4.0mm, 100/16–6.0mm, and 100/16–8.0mm twin needles. My favorite SCHMETZ twin needle is the 4.0/80. SCHMETZ twin needles 4.0/80 The reasons it’s my favorite are: – It’s the perfect width for sewing down bias tape. – It creates evenly spaced parallel lines on sewing projects. – It’s great for quilting consistent, parallel lines on quilts. If using denim for a project, the SCHMETZ #1771 Twin Needle Carded – 100/16 – 4.0mm, paired with Gütermann Threads 30wt, mimics beautifully the twin lines found on jeans.

After moving to Ottawa in 1996, I joined my first guild. I took more courses and began to buy quilting books and lots of fabrics. Quilting has become my passion. I have made over 150 more quilts since then, and have never looked back. I now share my knowledge of quilting by teaching and doing presentations, and blogging! previous post Best SCHMETZ needle sizes for 30wt & 12wt Gütermann Threads next post Essential SCHMETZ needles for specialty sewing and smooth stitching YOU MAY ALSO LIKE...
