I used a modified seed stitch. Instead of a dc, I used a tc & kept the sc the same. Makes for a much more pronounced nubby, perfect for an invigorating bath or shower session. Making it a bright color makes interesting for kids, not to mention brightening up your stall or tub area!
I made them (I only photographed one but made several) with an opening for a thumb since sometimes you need to grip something, like a gel or soap.
As a gift, it’s perfect ‘cause you can make 1 in about an hour!
