I have just published my fourth pdf tutorial on Boundweave techniques, which is available to purchase and download from the Shop section of my website. These detailed and illustrated tutorials are each in the form of a full workshop, and contain all the information you need to weave a sampler of colourful motifs and learn how to create your own designs.
The fourth tutorial, Further Adventures in Boundweave, covers 2/2 twill and 2/2 twill on Opposites. On payment a link is immediately provided to download the pdf.
