Szabóné Csiby Hajnalka of The Netherlands, goes by Tiszi which I assume is her nickname and also the name of her shop, Tiszi.
She creates some really pretty beaded jewelry tutorials which are great if you love using different kinds of beads. Her mandalas and earrings are my favorites. I like how she often uses very small seed beads to “outline” her designs such as her Christmas bell earrings.
