Wonderful resources if you are interested in acrylic products and techniques. You will find dozens of ways to combine mediums and color to achieve various effects and to paint on a number of supports (paper, fabric, canvas, glass, metal). Though based on the Golden line of products many techniques can be used with other similar products. When the ingredients in certain products (such as soft modeling paste) are too different from what is found in similar products of other companies, the author makes this known. The spiral bound book makes it easy to refer to (it stays open).This book is fabulous if you want to expand your technical know how or simply transfer your knowledge to other supports than paper and canvas.
