Liz Morrow is one of my stitching heros. I just adore her lovely Bargello projects. Her newest ebook is an advanced course in 4-way Bargello.
Here’s what she says about it: ” This is a class in a box! Except there is no box! Expanding 4-Way is a set of instructions for 3 Bargello Techniques, one leads to another: 4-Way, Combination 4-Way and Four-Way 4-Way. You will learn how to set up each technique and stitch it using any Bargello pattern. There is a project for each technique to get you started.”
