Good Afternoon, Clover makes a needle called "Black Gold Needles" which are available in a variety of sizes. They are specially polished with Black Plating - Titanium and are black to look at- with a gold color at the end where the eye of the needle is located.
These needles need to have you run your finger up and down once, to revive the memory in the needle and will not break as easily as other regular needles, due to this memory factor. The needle pierces smoothly through fabric and causes less stress on those fingers suffering from arthritis and other inflictions. They are usually sold 6 in a package. I have seen them in sizes 9, 10, 11 and twelve. They are a little more expensive, however well worth the value you get.
Needles are stamped 2 at a time, with thousands in a row. Needle Eyes have a rough side "The wrong side" and a "Right Side", when they are made they are punched, and the up side is therefore the "Right" side and the bottom is the "Wrong Side".
When you are trying to put thread into the eye of a needle, do the following:
first trim off the end of the thread you are working with, then attempt to put this thread into the eye = if it doesn't thread easily, you are probably trying to thread the "wrong side". Turn the needle eye over to the "Right side" and you will find it is much easier to thread than the wrong side.
I found this information thru watching a video on needle making, when I was taking a sewing machine class and it has helped me immensely.....just in case you are interested - I hope this will assist someone else as well.
Have a great weekend
