All my patterns use US terminology.

Little Dust Daisy is a bookmark simple and easy to make. I honestly don’t know how much yarn you need to use. Just use your scrap yarn, some fantasy and maybe 30 minutes of your time. You don’t need to know the gauge or the yarn weight. The design works with every yarn you have and with all the colours you like, of course.
This bookmark is just a way to not waste your little scraps of yarn and don’t just let them collect dust. Instead you can make something useful for you and your dear ones.
All of us crochet lovers have a lot of yarn, I know. Sometimes, maybe a lot of times, we don’t really need to buy a new skein to make something precious and satisfying. Sometimes just getting rid of those dusty scraps brings a lot of satisfaction.
This is a little step in the path of slow living. We usually don’t really need to hurry all the time. Am I right?
Enjoy your time then, bring some yarn and the matching hook and slowly crochet your lovely bookmark.

Gauge is not necessary for this project. Size will be determined by hook and yarn selection.
