I'm diabetic and ever since 2017 I have been gathering the colorful caps of the needles I use to text my bloodsugar and every January (with Rainbow Dash Day of Equestria Daily comming up) I assemble them as a mosaik of Rainbow Dash.
Here are the mosaics of 2018 and 2019.
Same as last year a whole year of gathering caps has not expanded the mosaic as much as I would have hoped… but who knows what she will look like in a year from now ;)
