I too had some really trying times in attaching the end binding. Then I found the binding tool which has printed instructions right on the tool. I purchased it at a quilt show after seeing a demonstration and still could not make it work... At the next show I returned to the vendor for a repeat demo and still could not manage "the foolish thing" so thankful for my sister who told me to refer to a video on YouTube which demo'd the tool. The first couple of times I had to have my laptop right there on my cutting table, but it was worth it. This tool is so helpful once you know how to use it!!
