- a thin dried stem (mine is slightly less then 1 mm thick), like the dried flower in the photo, but nature has more thin hollow stems
- a pencil lead from a penlike pencil you normally 'feed' those to write
- a hobbyfile like mine, an emoryboard, or a piece of sandpaper stuck to something flat
- paint if you like (spraypaint works best) and then also doublesided tape to hold the pencil up
1) gently file the lead by rolling over it with the file or sandpaper, until it's thin enough to fit the hollow inside of your stem.
2) And very gently put it in the stem. If it doesn't go further, don't push, you might need to file a bit more as I had to in the left-down picture. It does break sometimes, then you can make a smaller pencil from that, a 'used' one. It can be loose a bit and the lead can shift inside the pencil, then you can put a tiny bit of superglue to the lead on the side it comes out and push it in. That way it should stay put.
3) If you want you can paint now, put it with the back on a piece of doublesided tape and (spray)paint.
4) After drying you can file/sand the point and the back till they look like the real deal.
