What is the best way for one to go about weaving a draft for 12 or 14 harnesses on a 16 shaft loom? I've been researching shaft conversions but mostly I turn up how to weave a more complex pattern on a loom with fewer shafts (weaving an 8 harness draft on 4 harnesses, for example), rather than the opposite. I recently purchaced a 16 harness Ashford loom, and will need to weave some drafts requiring only 12 or 14. The harnesses are easily removed in this loom-- can you take out the ones you don't need, or will that cause the loom to be out of balance during weaving? The other option I thought of is using the extra harnesses to create a nice selvedge...or is it easy to convert a pattern from fewer to more harnesses, keeping the design intact? Does anyone have any good techniques for this?
