<p>I have refurbished this vertical tapestry loom but I don&#39;t know what type it is. I thought it was a Glimarka but they say it definately is not. I would like to know what kind of loom it is and I also need to know how to warp it. In particular the beams (top and bottom) have a slot that a 1x1 wood slat fits in. I suspect it is to hold the warp in place but I can&#39;t figure out how?? Any help is appreciated. Thank you.&nbsp;</p>
