Butterfly shaped push-pins and a flower-shaped support that has a dual purpose: organize the pins and serve as a paperweight.
The wings of the butterfly make it easier for you to insert and remove the pins.
The nails I used are: COUSIN CORPORATION. An image shows the product.
The butterflies don't need support and there are two models (the moreadj has a more adjusted plug to insert in the pin). I recommend you to try both and see which result better or you can also add glue (an explanation video in instagram shows how to make the pins).
For the stem you can print it solid or print it empty with its lid, to fill it with sand, as is shown in the videos at my instagram!
