I have sold hundreds of these sets on another website, they have been fully tested and proven for the past 5 years. The wire guides and mandrel kit help in setting up your Viking knitting. A great time saver: Place the wooden wire guide you need for your Viking knit project on top of the dowel, make loops through the holes in the guides with spare wire leaving only enough room for threading your project wire through on the bottom and you're ready to start. The holes are evenly spaced around the dowel so that there is no fiddling with long wire loops, elastic or tape to start your weaving. Updated and redesigned to minimize waste and help enable me to up-cycle my leftover wood more efficiently. New square shaped guides have a circle of holes evenly spaced around the dowel to guide your wire loops. This new design also helps with placing the guides on and off the dowels. Handmade from solid wood, the kit includes 8 one inch guides to fit 1/4", 3/8" and 1/2" dowels which are included in the set. Made to order, it takes approximately 1-3 weeks to ship out. I ship orders out in the order they are received and completed.
