This needle set is the only one you'll need for any sort of hand sewing, especially using our conductive thread and wearable electronics parts.
Each pack contains 20 gold-eye sharps, with eye sizes ranging from #3 (1.75" long) to #9 (1.35" long). The two #3's (the largest) are too large to pass through the sewable coin cell holder but otherwise are easy to use and thread. The four #9's (the smallest) are a little difficult to thread so you may not want to use them with our conductive thread - they'll be easier to use with normal thread however. The remaining 14 needles are perfect for use with our 2-ply stainless conductive thread, 3-ply stainless conductive thread or stainless conductive thin yarn.
