I started getting curious about what all the numbers really mean. That’s my geeky side showing. I found that Schmetz has a nice handy downloadable guide.
It turns out that on our preferred quilting needle, the 130/705 H part means that it’s for a home/household sewing machine (vs. industrial), and the 90 is the diameter of the part of the needle above the pointy part. Schmetz calls that the blade. So for instance , an 80 is a smaller diameter needle. I’m still not clear on what the 14 part of the needle means. Maybe the eye size?
Anyway, in one fell swoop, I increased my knowledge of needles by about 500% so I thought I’d share. Hopefully not needlessly.
Here in the home office, we use our needles until they’re not sharp. Which is usually after piecing 1-3 quilts. Or quilting one quilt. Or when the needle runs over something it should not be running over (like a pin or a finger). Or when fabric points start getting pushed into the plate of the sewing machine. And paper piecing is murder on sharp needles. I don’t think there’s any way around that.
