I made these using SWTC Bamboo in white. You hold 2 strands together so its nice and thick.
Knit in the round on DPNs, and closed with a snap. Or you could make a buttonhole to close if you prefer. This soap sweater could be used a few times which is why I made it to be able to open/close, but you could sew it up at both ends if you prefer to only use a soap sweater once.
Bamboo is soooooo nice and soft and absorbs heaps of water so these are great to shower with.

Please let me know if there is any problems with the pattern, I’m not a professional designer! Thanks :-)
