I have done a few machine knitted hats in multiple mediums. I am not really one for doing much in mixing different types of yarns, but these turned out pretty cute.
I mixed worsted, ribbon, eyelash, fun fur yarns with knit sections and purl sections. These were done on a Brother bulky machine with out a ribber so the seaming is just being done now.
I do want to try some of these on the looms so that I do not have to seam them. That sure is a great advantage of using a round loom over a flat bed machine. The machine is quicker, no doubt about that, but the seaming time overrides the faster time of knitting. It is not that I am slow in seaming but the mixed mediums I am handling more carefully as some are open on the sides and need special care to seam them properly.
I will be posting pictures in the next couple of days.
