Description Acrylic Practice board. A perfect template for henna artists to practice full bridal designs. Are you looking to plan your design layouts, try new design elements ? The acrylic hand is a perfect template set to practice on & refine henna skills. You can wash off the henna with water, or scrape the dry henna away. We recommend using only 100% natural henna on the acrylic templates to avoid staining the acrylic. Henna containing chemical dyes will stain the acrylic & the templates will be unusable if that happens. Please do a little patch test with any henna you are going to use on the acrylic templates.
