Hidden Row Mastery
with Sam Hynes

Sam Hynes
Master the art of the hidden row using my go-to wefts: the genius weft. This is a hands-on class, taking a deep dive into everything weft. Struggling with your hidden rows or are you a beginner to weft hidden rows? This is the class for you. We'll cover everything you need to know about genius wefts including placement, beading, stacking the wefts, and securing. I will be demonstrating a full head placement on a mannequin head, then guiding you through your own install. By the end of the day you will know how to do a full head install using a range of techniques and stitching styles. We'll also talk color matching, pricing, and so much more as I share my secrets to my most requested install. A mini kit and KOVI practice hair will be provided.
