I made a challenge to draw Italian sweets for 30 days, but during the process I was struggling how to show texture of the sugar or powder in an interesting way so I took my daughter's candies (don't tell her :)) and I dipped it in ink and created these traces of sugar that I used in the illustrator and even to create a pattern.

If you are interested to see how I used them in the other illustrations, you can follow my Italian sweets challenge drawing on IG
