Pierre Fouché introduces the idea of using bobbin lace ground stitches like brushstrokes, using an understanding of the basic building block of each stitch and how it interacts with the net. With careful text and image explanations. Pierre demonstrates that free-form grounds drawn with a variety of these building blocks can have the expressive character of a charcoal drawing or a watercolour painting. You will learn the basic units of three ground stitch families: two-pair crossings in bias- and hexagonally arranged nets (nets and honeycombs), four-pair crossings (rose grounds and small snowflakes), and finally, three variations on six-pair crossings and their interactions with the net (large snowflakes). You will practise applying these basic units in a free-form, doodle-like design of your own, in a process similar to playing Tetris with lace ground motif-shaped tiles or building a wall with differently shaped Lego bricks. Completing the exercises and the course sampler design will give you a greater understanding of the basic geometry of the most popular ground stitches, which will enrich your craft in numerous ways: being able to recognize a variety of grounds that can be worked on an existing pricking will provide the freedom to easily adapt existing designs with grounds of your own choice. It will also unlock the art of rapid ground exchanges within the same design area which can have many creative applications. All levels of lacemakers can benefit from this design system, even absolute beginners.
