Thanks Frank for urging me to share my creation with others that I have already shared with you. In my "beginning to learn weaving" [and using low cost knitting yarn] I wondered what 2 different color yarns would look like together in a weave. I had just received my single shuttle with 10 bobbins order - so I had bobbins. Being a retired electrician I know for years we would heat and bend pvc pipe and I had some scrap materials. The bobbins go on a lightly sanded piece of 1/4 dowel rod so to fabricate and attach two pieces of scrap wood to hold the dowel and bobbins was the design challenge. In total with the scrap material, this cost about 20 minutes worth of power for the heat gun and two wood screws. It could use improvement modifications on side holes for the yarn outlets but it does work, slides well, did not nosedive or stick in the warp.
