My mother currently owns a union loom that she purchased from her former mother-in-law, Agnes Stremler Groenhof. This is the loom that my mother (hopefully) will pass along to me! As far as I know, my grandmother Agnes worked in the textile industry in Michigan and at one point purchased or received this Union Loom manufactured by the Union Loom Works in Boonville, N.Y. I don't have any memories of my grandmother working the loom but she did save a clipping from the Holland Sentinel showing her working the loom at a craft fair (which is posted above).
I do have lots of memories of my own mother working on the loom making rag rugs. I can still hear the banging when she pulled on the reed piece to tighten up the weave. My mother, and apparently my grandmother, always worked standing up since there is an extra board attached to the bottom of the loom to make it taller. (My grandmother was about 6 feet tall, as am I!)
The reason I am bring up the loom now is because my mother asked me to find a new source of warp since she hasn't purchased any in a long time and will need some more soon. So I was looking around the internet and finding out stuff about this loom and where to get warp. It looks like I am fortunate to have an original instruction manual. So at some point, I will scan this booklet and post it to this site (or link to its location) so that anyone looking for a copy can get what they need.
