I have a quick tip for you about safely getting rid of your used sewing needles. You do change out your sewing machine needles after every eight hours or so of sewing don't you? I know people who change those needles every time they load a new bobbin! I'm not that fanatical but I do know that a sharp needle makes a world of difference when I'm piecing and it's absolutely essential to machine embroidery. In fact after proper stabilizing I would say a dull needle causes the most problems in machine embroidery.
If you change your needle as much as you should what are going to do with all those dull needles? PLEASE, don't just throw them in the trash! They are a hazard to yourself and everyone else so some form of containment is a great idea.
I use an old medicine container with a child proof lid. I poke a hole in the top and whenever I change a needle I can just drop the used needle in. Once the medicine bottle is full I just throw it away and start a new one.
You may be able to see a broken needle or two in there as well as some extra small rotary blades.
Bonus point: I use those old, dull needles to display my small projects in the sewing room! They go into the dry wall easily with just a tiny hole.
Until next time,
