I am a new weaver. I have read in varoius books that I should get familiar with both styles of dressing the loom; back to front and front to back. I learned front to back. I have attemped back to front once but found it awkward. The Deb Chandler video " 4 harness weaving " mentions a warping aid to assist with back to front . It is a frame that holds the lease sticks in place I imagine , maintianing the distance between the two. and keeping the lease sticks in place. I have looked online so far for this device but I am not really sure what it would be called. I have had little to no luck searching" warping aid" or "back to front warping aid". If someone knows where I might find this device please help. I would like to be versed in both techniques. Thank you.
