Thought I'd see if I could draw on others' experience here. I have a demo upcoming at a Wool Arts event to support local farms and I'm bringing a 4H Harrisville studio 22" floor loom and a Leclerc Medico table loom that'll be new to me (don't even have it yet). I feel I should use wool, even though it's not required. As this is taking place in a barn, I'm not keen on letting people treadle on the Harrisville so I'm looking for ideas to show the flow of the work myself but also have something that gives a "wow" factor as the design develops without being hard for me to stop and start (I know, that's everything at once!); I'll warp something on the table loom that'll be hands-on for spectators so probably just a simple point twill or rose-path there or even a tartan, which everyone seems to love. I don't often weave with wool anymore. Anyone have some "this worked great for me" memories to share here; or even "don't do this!" I have two weeks to prepare and Harrisville Designs is local to me so I'd love to use their yarns and have Shetland in the stash. I'm a moderately experienced weaver, love overshot but am thinking I should stick to one shuttle for simplicity sake. This loom, I should add, is an older one with only 4 treadles and direct tie-up so a complicated tie-up and simple weave isn't the answer. This isn't usually a problem for me at home but in a demo setting? Caution is the better part of wisdom, I think.
