Hi Emsu! Almost all the techniques in Heirloom Sewing Essential Techniques and Heirloom Sewing More Classic Techniques can be done on any sewing machine in good working order, as long as it has an adjustable zigzag. As far as machine recommendations, I always tell students to buy the brand with the best dealer in your area, because you really need a good dealer for education and maintenance. I look forward to hearing how you like my classes!
